I really don't want to defend Richards or what he did/said. I just want to make the point that if someone loses it, the remarks they make don't necessarily reveal hidden bias or hate.
LJ, I know you don't like to be called a car salesman. I understand why and that's cool. But I also know if I want to hurt your feelings/piss you off, that will do it. That doesn't mean I secretly think you are a car salesman, but don't say it the rest of the time, to be politically correct.
Not the best example but I hope you follow me drift.
Racist remarks? Certainly. Racist? Not necessarily.
When someone gets aggravated to the point they snap out, completely lose their cool, they will likely say anything they can think of to hurt the target's feelings. They will seize on anything discernible about their target, color, ethnicity, sex, size, clothing and distinguishing marks like tattoos, birth defects or religious medals. Anything to make the insults as personal as possible.
You don't have to be a closet racist to be aware of racist insults. As a matter of fact, a true racist, would be less aware the remarks are insulting.
During a tirade, all the things you've learned are politically correct, become ammunition when turned around.
