I have to echo BOb's approach. I tend to make a statement about what I think and then leave it there. If I am convinced by someone's argument, then I try to respond with an acknowledgement. If another person holds a pov that is abhorrent to me, I tend to jump in for a few posts and then dissolve to background if the "debate" continues without any sign of shifting views. It's too easy to have a discussion devolve into flame wars on the internet, in my experience.
