It sounds like we're talking about different things and I don't disagree with what you described. In the example you used, where people are unaware of where the line is, I would fully expect that a person caught unaware, would, without trouble, be able to deduce the reason.

It's the hardline bigots who, again in my experience, cannot tolerate being confronted and feign ignorance in an attempt to misdirect. I'm pretty sure, if you found yourself face to face with one of these, you would be able to identify them easily.
