22. Fear

Islam is based on fear. Fear of death that makes a lot of people believe in afterlife to avoid it. Fear of Hell that makes them follow religion's teachings to avoid burning for eternity. Fear of having sex and being whipped to death. And fear of conversion and getting killed for it. Fear of the unfair life that they live which makes them believe in a God who's responsible for it, who does everything for a reason, even if they can't see it.
Islam spread with the edge of the sword, not with the strength of its beliefs.
And that means that its source is not a wise, merciful god, but a bloodthirsty childish one. Which Allah is most of the time.

21. Gods with Names

The fact that Allah has a name and is called by it raises many questions.
Why would he have a name? Isn't that a human character? Or does he just go by it? if so, why are Muslims so fussy about calling their god Allah and not God in English?
If not, how did he know that was his name? can he change it? did he have parents who named him that?
Why is the name Allah so close to the word Ilah which means a god in Arabic?
there's something in Arabic that is called the "exaggeration form", that for example if you have the word "katil" which means killer, the "exaggeration form" of it "kattal" changes the meaning to the worst (or best) killer and so on. The word "Allah" is very close to being the "exaggeration form" of Ilah, so could it be that Muhammed wanted to have one god in his religion that's stronger than all his people's Ilahs, so he simply used the "exaggeration form" to call him like that?
I can't answer that, but it sure raises a good question whether Muhammed actually talked to Allah or not.
PS:Same goes for the words, Jehovah, the Lord, Jesus etc.

20. Scientific Errors in the Quran

There are numerous scientifically inaccurate assumptions in the Quran, here are some of them:
1. The sun sets in a lake of water. (this is typical as people usually saw the son disappearing behind the sea, so Muhammed probably thought it was miraculous that the huge son goes into water and comes back up the other day).

2. The sky is some kind of a roof. (probably people thought it's like a big dome as it was colored and curvatured, Muhammed bragged that his god Allah could raise such a big dome with no supports or poles).

3. Animals talk to humans. As in when Suleiman the prophet (Jewish King Solomon) heard ants talking and had a little chat with one of them.

4. Fire is a kind of matter of which Jinni's are made.
5. Humans are made of mud. (Probably because when humans die, they disintegrate in the soil).
6. Stars are light sources in the sky.
7. The obvious contradiction with the theory of Evolution.
There are many others of miracles, creatures, and weird assumptions, but only a few are enough.

19. Sexism

This is a huge thing in Islam and other religions. Inequality between men and women exists ever since the first creation of Adam and Eve who was created from a rib of his. Here's a list of the other sexist parts of Islam:
1. A man can marry four women, a woman can only marry one man.
2. A son inherits twice as much as a daughter. (The cases of inheritance are numerous, but women always get less than men).
3. Women should cover their body except for their face, hands, and feet, men should only cover the area from their bellybutton to their knee.
4. Women are minors who aren't allowed to travel alone, their guardian changes after marriage from the father to the husband.
5. Women are minors who cannot go out or allow someone in without the assent of their guardians.
6. When testifying, a woman's testimony is one half a man's.
This discrimination is supposedly because of the part Eve played in seducing Adam to commit the original sin. Another huge anomaly, punishing someone for another's fault. But that's not the subject, the point is, God cannot be sexist, by definition, but he obviously is.

18. The Numerous Choices

There are numerous religious sects and cults and beliefs. And in order to be able to choose the only one that is right, you have to neutrally examine all of them. That's an almost impossible process, since there are numerous versions of every religion, in Islam, they're not only Sinna and Shi3a, in Shi-ism there are many differences between "scholars" and Ayatollah's, and they all have their "reason" for believing in their way, and throughout history, religious statutes and moral codes have varied in most religions. That's not it, there are many versions of each and every religion, I've never seen two believers who agreed on everything in their religion.
This makes it very hard to examine religions. Besides, it's already hard to be unbiased to your own religion when examining other ones, because as I said before, people have been bombarded with it ever since their childhood, and it's a part of their system.
Therefore one can say that since there are so many ways to God then there is no way of realizing which one is the only true one and which others are not. Therefore you can't believe in any of them. So if we do not examine religions, we're not true believers and are only inheriting them, and if we are we'll still be biased to what we already believe in, and it would be impossible to examine every religious idea.
Besides suppose two religions made equally as much sense to you, how would you know that one is from God and the other one is man-made? This nullifies the constant imploring that Muslims, for example, do for others to examine their religion, As it would be both unfair and meaningless to examine only one religion and believe in it.

For me, I confess that I haven't examined all religions there are or had been, only the three Abraham-ic ones. I choose to believe in science that only has one version of the truth, one that I can perceive and that does make sense. It doesn't make sense to me that there is a creator, because ever since I heard that, questions in my mind started popping about the possibility of that and eventually I reached the conclusion that there is no creator and that religions are man-made.

17. Belief is not heritable

It's impossible to decide which theory of God is true. People will most probably inherit their religion from their fathers who themselves have inherited it from THEIR fathers and so on.
Even if one does observe other religions and philosophies, he will always be predisposed to the religion of his own. He would feel like he's on a divine quest to prove other religions wrong and only his own to be right.
It's just as much impossible to decide which religion makes more sense than the other, simply because they don't. Religion is not about making sense. Actually I don't know what Religion is about. In here, it's mostly about identity, something that is a domineering part of your culture and of your life. It's not something you choose, it's something that's imposed on you. If you repudiate it, you become a pariah, an outsider, someone whom everyone concurs to abhor. It's not really about how valuable the concepts the religion involves, nor about how much of a benefit they are, it's more about tradition and customs, and by relinquishing your religion, your people will feel you're relinquishing them.

16. Scary Heaven

The idea of Eternity and infinity is vague and incomprehensible. What if I don't care about the virgins and the rivers of wine and water that are in Heaven? All the pleasures that Islam promises its believers are based on the basic needs of humans, food and sex. I find them to be grossly benign to the evolved human being. I can achieve these pleasures during life and I'm sure I'll be bored of them during it too.
When I tell believers of this, they respond that in Heaven, God will make us different and for men, their virility will be some number times as much (which obviously is the only thing that matters).
Eternity and the idea of living forever may sound amiable at first but after thinking of what to do and why living, not that much.
