Similarly, there are many on the left that paint with way-to-broad of a brush. Those people don't seem to know the difference between conservative and Republican, much less the difference between big-R and little-r. So along those lines, I think arch's response is easier to understand.
You are definitely correct in that too many people judge others by group rather than individual. It takes a lot less effort.
As for arch's response, I think he knew exactly what OCD meant but was using a common confusion to distract from the discussion. I could be wrong and will let arch clarify when he gets back on the board. But I've seen him use that technique numerous times before.
