Psychology behind debating? Or is it just fun to stir the pot once in a while?

There's nothing wrong with enjoying debates. I enjoy them, at least while my opponent is vaguely making an effort to be honest.

However I think they are of benefit to onlookers. If an atheist's arguments are carefully constructed and accurate, and if the responses are emotional and fallacy ridden, it may make some people think that we actually have some valid points.

I would bet that thousands of lurkers have de-converted on the strength of reading/listening to arguments all over the web and slowly absorbing it all.

It also helps to clear up inaccurate preconceptions about what atheism is, and what atheists "are like". And to show how many of us there are out there, to help people feel more comfortable with admitting what they are when the time comes.
