Who is the enemy?

I recently ran across a blog by a former Navy Warrant Officer called StoneKettle. It's fairly entertaining and well written (though with a fairly aggressively unfriendly notice about copying), but I mostly wanted to point out to this golden quote that succinctly summarizes much of what passes for political debate in this country.

If you see your neighbors as the enemy, it should come as little surprise when your elected officials do likewise.

I'm not really good at this, and not sure how to get around "the other side" doing this to you, but it's really important that we do. And, by extension, we need to have debates that are grounded in actual facts (because if you can't agree on those, the idea of compromise and agreement is impossible).
