conversations about religion

There are some mostly blameless persons who think of religion as a disease. After someone's declaration of religious commitments, the implicitly (or explicitly) expressed reaction is: "Oh, how'd that happen to you?" The conversation is then stifled because when someone comes down with an illness it's best not to talk about it, lest they be reminded of how terrible the situation really is. Jokes are made to lighten the mood. But then the conversation is limited by thoughts of "Dude, don't say that in front of the religious kid, he might be offended!" For religious people are judged to be judgmental, because religious people believe in right and wrong, and they take the idea of right and wrong seriously. The religion doesn't necessarily have to be any one in particular, but Christianity is often seen as the most judgmental and therefore the worst dis-ease to come down with. It seems that religious people need to make the argument that, hey, everyone believes in right and wrong, and it's not something to be scared of.
