Dont know, but when we say no one should be allowed , that means no communication exchange. So both of them should not come and meet in the same teritory. It is when the end of time. Forever separation is the solution for this debate.
Your belief system is a matter of your own personal thinking. Personally, I don't believe in a "God," and I think that religion has hindered progress, but when it comes to these matters, it's just best to leave it up to the person. Don't shove metaphoric junk down someone's throat.
I was watching a video from Fox news and they were like 'American Atheists are offending Christians by putting up atheist billboards' and then the guy from American Atheists was like "you guys are offending atheists with your posters hypocrites"
Personally I think the billboard thing is stupid, no one changes their beliefs because they saw a poster and they probably turn more people away that they get who side with them.
