For me three things about Islam I dislike most are
My mind can't except a person as my prophit who married 9 ys old friend's daughter at 53 in the pesence of dozen wives. Concept of paradise is nothing more than expression of oversexaulity.Even sex videos of today can't match it.
2-Disrespect for women
considering them half man,envloping them in clothes(fear that...), no freedom of movement(even can't visit Kaba without a mehrem), no right of divorce, alowing their husbands 4 marriges, hellworthy if disobey their husband........... Is this the religon which restored the respect of women.It makes a women property of man rather than a human being.It is better for a women to be burrired alive in the childhood than to live as a Muslim.
Got no place for music or fine art of any kind, prayer system harshest on the eath(hunger for month, 5-7 mosque visits a day), look at the hell conscept(burning in the fire, drinking pus, stinging by snakes and scorpions). This religon is definatly is a sick God's idea.
