To be honest I'm not entirely sure about this myself, perhaps I think that religion is an unhealthy mindset, i mean no offense, it's just my opinion, and i'm trying to work out what's going on in peeps heads.
I don't think many people here will be offended if you say religion is harmful to society.

The vast majority of us are anti-theistic.
And in all this im interested in the mindset of the muslim that leaves Islam, what has happened to you beautiful few that got you thinking that maybe there is no God.
Simple. I was not dogmatic by nature, so when I had doubts about the truth of Islam, I decided to investigate them and think for myself to reach the truth, and soon realised that Islam is just another man-made religion. In fact, I realised that everywhere on this planet, even remote tribes have a set of superstitions and rituals to explain various phenomena and to hope to control them through prayer, sacrifice etc.

What you have to realise about Muslims today is that because of crowd psychology (and other cognitive biases) people can't seem to see through their delusion. Also, nobody wants to be a social pariah, because that's what happens to open apostates in most Muslim communities, so they stick with the group no matter what.
This may sound really crazy but I really like the singing Muslims do about allah, but i always feel guilty listening to it and I wondered if there is such a thing as atheist arabic song in the style of Muslims singing to Allah?
The music I was refering to is on youtube here, watch?v=EAvlimEYEpQ
I still listen to beautiful Quranic recitation and adhan occasionally. Here are some beautiful adhans (call to prayer):
Mecca,
Jerusalem, and here is a
beautiful recitation of the Quran by a child which you might have seen already.
