How do you distinguish this from threatening those who might choose to employ black Americans in order to make a buck?
Again I fail to see why you needed to raise the issue of race at all.
Because in the case of racial bias, people are shocked and horrified. Yet in the case of national bias, people aren't. I'm attempting to point out that there are few good distinguishing principles between the two cases, so the dichotomy is unjustified.
In what sense are we using the term 'treat as badly'? Who do you mean by 'we'
I've repeatedly said that "treat badly" means "threaten with violence for engaging in mutually agreeable trade" and "we" means "organizations that purport to act on our behalf" (US Govt, white supremicist groups, etc).
