I don't get involved in religious politics nor do i take any sides in a religion vs religion, religion vs science or a religion vs athiesm debate.
If i have an opinion i'll voice it when it needs to be heard, other than that i won't disturb peoples peace for some self righteous gratification.
If people are genuinely happy with their lives then that's all that really matters, if i'm faced with someone who's attacking me for my beliefs or trying to convert me i'll respectfully remove myself from the situation while stating that i have my own beliefs and i'm happy with them.
If me and a friend get into a religious conversation i'll always issue a disclaimer at the start ... something along the lines of "hey before this goes any further, lets agree to halt if we see any chance that this could develope into an argument"
