With so many different viewpoints and religions, all claiming to be the one true one, there will always be someone you offend. As long as the opinion is put forward in a polite manner and not designed to flame or upset, then it's too bad if someone can't handle the opposing viewpoint.
If you can't take it, you shouldn't be contributing.
There are certain types who are only there to push their point of view and ram their religion down your throat, with no intention of joining in a rational discussion. They don't tend to last long on mine..
