The Christian/Atheist debate

I am becoming increasingly tired of the Christian/Atheist debate.
Below I made mention of the Dawkins-Lennox debate, but I'm not just thinking of that, I'm thinking closer to home.
Recently I have been having a few discussions with Atheists via facebook. Mainly I have been acting as an arbiter, or simply discussing the Bible on it's own terms. I'm not into the Philosophy, and neither am I qualified to answer. Plus it can be a little dry.

But all this makes me wonder.
Is Christianity engaging the Atheistic community helping, or is it increasing the problem?
Are we simply giving tools of rejection to those who might otherwise accept the Gospel?
It seems the more we defend, the more voices that become educated in atheistic thought and come against us.

I'm also finding that in discussion, when coming back to the Bible, so much more gets discussed and considered. I don't think I'll become an apologist. I just want to preach the Gospel man.
