I'm also an ex Muslim who's now atheist, but if I'm really honest, I don't think I was ever really a Muslim. I was born into it, yes, and I made all the motions and pretended to be a good, practicing Muslim to keep my family happy for about 20 years. But I also lived a double life since about the age of 10 or 11...
I am not Muslim because Islam is an oppressive religion which doesn't allow women any freedoms to think or act for themselves. Women are treated like and seen as possessions, objects which men control and who must obey their owners...that makes them no better than dogs or pets or a piece of furniture in the eyes of Islam...
Women are also not allowed to wear what they want because it will corrupt the men around them...yet no one ever blames the men who are staring...
Rape is also condoned because women have to drop what they're doing and go attend to their husbands needs, even if they don't want to...
Education is also frowned upon because it makes women too free thinking and gives them ideas that makes them difficult to control...
Restrictions on women are such that even plucking your eyebrows isn't allowed either...
The worst part for me is the fact that the quran condones violence, in the home, against non Muslims...and before anyone is quick to jump on all this and say its about how you interpret the Quran, if Islam were a religion that allowed people to make their own minds up about their lives and how they live it, it wouldn't be Islam...because the very word Islam is derived from the root meaning to surrender, submit or obey...
I really don't mean to offend anyone who is muslim and does believe in all this, but those are my opinions and what i have learned having read the Quran, the hadith's and attended classes to try and understand the religion better.
My parents and family are Muslim and do not agree with my decisions but that's their problem and the fact they've chosen not to accept their child no matter who they are or how they think, like parents and family should, they've shunned it and essentially cast me out which just reiterates my point about how Islam is not an open or accepting or tolerant religion.
