So Hi,
I think it is really hard to answer, since for example christian are helping AIDS being spreaded with the forbidding of condoms, islamic people are to prude and think their religion is the best and everybody must follow it, etc etc.
But isnt some of the stuff helping, like in the ealier days a lot of wars were started because someone fucked someones else wife, harder in islam since all the woman are ripped off their sexual appell. This=less wars
Arent christian-nuns helping shelterless people?
So better off without or with them.
Its up for you to decide!
