So who are the aggressors on this forum, the Christians or the Atheists?

I welcome debate, but when posts get ugly, who is responsible? Do more atheists or Christians tend to bring the debate down? I'm a Christian but know I've used sarcasm to make a point, so I'm not giving myself a p. But, I umed atheists would be more pive towards Christianity, even more apathetic. What I see on this forum however, is a desire to "teach us a lesson" about our beliefs. But, Christians tend to want to lecture instead of show the love we are supposed to, so who instigates the most?
