I couldn't care less what religion someone is, or if they have no religion at all (unless that person believes that their religion requires that they kill me or convert me.....then I guess I care). I prefer to judge people on their day to day actions, how they treat others, their position on government, etc...
This ^^^^ - as a Christian, I believe in letting others make their own mistakes. The good Lord knows I've made enough of my own. Don't push your religion on me - 'cause I won't push mine on you. There's already enough strife in this world.
