Meh, I'm Christian.
And I'm not even casual Christian, I'm pretty religious.
But even I realize that this is the internet, and I don't take any offence if people choose to be insulting, because I know most people here aren't doing it to offend others, they're doing it for a laugh, and I can appreciate that.
For example, if I were black, I wouldn't get angry with tribal comments or jokes, hey, I might even join in.
All in all, most people aren't going to share your views, and you need to accept that; but if I can give you one piece of advice, it's that if you have a strong belief, stick to it, and if anyone tells you it's stupid, defend your opinion.
