My view and reasons for them. Atheist and Christians welcome here. (short)

Am I right in thinking that this guy is placing himself in a middle ground, not being an atheist or a theist?

That's fine, if you use certain definitions for words. But that doesn't stop him being necessarily a theist or an atheist by our (common) definitions. So he would be carrying over a sizable chunk of people he's referring to as atheists (or theists) into his middle-ground camp, without acknowledging this. It's a tactic I've seen many times before (possibly due to misunderstandings, possibly not, but once this has been pointed out, that excuse disappears). It's a way of trying to feel superior to both sides. He's assuming all atheists take a stronger position than they necessarily do.

He sounds way more like a theist than an atheist to me as it happens, but as usual, the word "God" has no coherent meaning so the point is moot.
