Proven by polls and science is the fact that even Catholic priests get more ass than the typical atheist. This results in the atheist having to take an alternate path to survive, since no one wants to get buttfucked by a neckbearded yeti who thinks it knows everything.
Since atheists fail majorly at sex and no one wants them, there is no need to promote abstinence amoung their basement-dwelling, unwashed masses. This proves the fact that atheists are the leading cause of AIDS, STDs, and unwanted pregnancies.
This leads us to the conclusion that:
- Atheists have thin no dicks
- If there were no atheists, AIDS would be a rare STD (Since most of Africa are pretty much like atheists)
