I'm not a religious person and I was not raised in a religious household. I've come across many people that were Christian. I would say that at least 90% of them took such a hardline and fanatical stance that it turned me off from even asking them about what they were into.
My experience with religious people was basically summed up like this: Confrontation, Hostility and Intrusion. I actually ended up in a few fights over this stuff. (None that I actually started) I honestly don't care if people are religious or not. Hey, whatever gets you through this go around on this blue ball is fine with me.
However, when you have people that will actually throw a punch at you, come to your home and bother you (although they say that they are just "raising donations". Sorry, it's you being bothersome. You want money? Pass the plate during service. Don't come to my home and bother me.) Then, when you say, 'sorry, I'm not interested' and then they launch into some tirade about how I am going to hell. Sorry, but you can get lost.
I don't need anyone feeling sorry for me, taking pity, etc. I abhor the idea of anyone taking pity on me for any reason. I didn't seek it out. So, don't bother with that.
However, I have met a very tiny minority of people that are religious and they were cool with the fact that I wasn't religious. People like that will always have my respect.
