Probably 9/11 opened my eyes. I realized that Islam at its best couldnt re-invent itself or adapt to the changing world. I realized also its the reason for all failures of Arabs and Muslims. Yet Islam is apologetic to every medieval notion, the way it treats women, other non-believers and religions, solving simple problems of life other than Halal/Haram and just branding others as blasphemous. This religion goes against my mind and values, that way I left it
