You are correct that some just want to start an argument, some are curious and want clarification on an answer and others want to prove that the answerer is wrong in their belief. I seriously doubt that many people are going to change their religion because of these threads. I think the best we can hope for is that we understand the other side better and maybe not just assume everything we hear about them is true, be they Catholic, Protestant, Muslim, one of the Eastern religions or athiest. I will admit that I have been guilty of intolerance and given answers that in retrospect could have been better phrased. I will say that I am a better Catholic because of this site and I hope that non-Catholics are getting a better understanding of us.
