> The corruption/abuse item is not part of the research, which is why I separated that as "I suspect"

My main point was that the theory was labeled as something you suspect, but the evidence you listed to back up that theory sounded like it was being presented as fact. You've provided resources to back up the claim, at least to some degree (as you note), which is what I was looking for, so thanks. :)

> You could, and I'd actually be interested to see any research on the topic because I've not thought about that one but it does match our general experiences about exposure and tolerance to social differences.

I don't have any, but I also would be interested to see it. I was using it as an example of something that sounded true and that I suspected was true that I had no real evidence of, and thus should be hesitant to assert as true. Unfortunately, by its nature that makes it interesting to a certain type of person, so it ends up teasing us. :/
