okay.
first paragraph? entirely wrong.
second paragraph, i wont deny. Christianity and other religions may have done one good thing. give peope a sense of morals and help suppress a fear of death.
back to the first paragraph. we have no factually, scientifically proven evidence that there is a god, meaning if they existed, we dont even know if they held back what you classify as "sin". More muder and wars without a god? see the wikipedia page for "list of religious wars". without religion, many of those wars would never have happen. More abortion and gay people? You're saying thats a bad thing, which is just bigotry at its finest, and i am disgusted by you. You say abortion is bad, but what if someone was raped and didnt want the child? You're saying they should have to carry the baby? and gay people? that isnt changable. gay people come from all different households. my gay brother was confused as to why he only felt attraction to men as he didnt kniw what a gay person was, so he looked it up. being gay isnt a choice. more pedophiles and stealing? again, you're assuming that there is a god. plus, havent you heard of all the pedophile priests?
all in all, i will not deny that believing in a god may be good for some, but it does not mean that if there isnt one that all this bad stuff will happen.
