Hadiths and Islamic Fundamentalism

I just read an article on a website. I guy I know has been sued for Islamic terrorism. He's an Italian convert living in my city.
I cannot understand how a somewhat intelligent and cultured young man can change so much, throw his culture in the garbage bin and decide to embrace the most intolerant, racist, hateful and misogynist kind of religion I have met so far.
I mean: culture should make you open minded.
If your mind becomes narrow... well, something went wrong. Very wrong.
I don't blame Islam as such for this. Islam is basically a peaceful religion even if it doesn't stand out as to religious tolerance. Or better, it does, when muslims want their religion to be accepted and respected. Not the same when it's their turn to respect others.
I am not blaming Islam in general. I have a lot of muslim friends, the father of my girls is a muslim too, and most of them are peaceful and kind people I like spending my time with. I also have to say I have received a great help from them. But unfortunately muslims have their fundamentalist wing. And this is the Islam I won't ever respect.

If you rely on the Quran alone, you can see that it is a book for open minded people. A book designed to regulate human life and to protect the environment. If you want to read a wonderful book about this, you can check this link.
The real problem of Islam is that most of its followers rely on a huge and despicable pile of sayings attributed to Prophet Muhammad and called the hadith. This is the source of: discrimination, hate, misogyny, ignorance, bad habits, and I could go on for weeks...
NO ONE of these sayings can be attributed to Muhammad with certainty.
More so if - as the same Muslims affirm - Muhammad was the perfect man.
Here you can find a detailed and clear explanation of the reason why all this crap should be forgotten and deleted from human history.

The Quran does not promote violence. Hadiths do.
The Quran teaches not to disrespect other human beings, whatever their faith may be. Hadiths do not show the same level of tolerance and respect for other faiths.
The Quran does not desrespect, isolate, humiliate women. Hadiths do.
The Quran does not contain stupid, insane or meaningless practices. 90% of the Hadiths is made by them.
The Quran teaches men how to live a happy life in harmony between themselves and with the environment. Hadiths enslave men to a long and sometimes funny series of debatable practices that should help them to reach the Garden. Well, if I have to live like an robot to reach that Garden, then I am quite sure it's a place I wouldn't like to live in.
The Quran doesn't depict religion as an accumulation of points at the end of which you win a place in Paradise. Hadiths base their "authority" exactly on this: if you don't act as prescribed, you don't get a point. That's all.

Thinking with my head is a rule I cannot fail to follow.
I cannot follow any rule or commandment that asks me to behave in a way that doesn't agree with my reason and with my feelings.
I guess that love and respect towards other human beings is the very fundamental religion we have.
Everything else is a detail.
Ignore details when they would make you act as a non-human being.
