Great article! As a member of a mixed-race/ethnicity (first generation American, not Black) family for 3+ generations, I can assure you that these 'white actors' are part of these settings. There is always--and I mean ALWAYS--in a larger family, a few conservative-libertarian brown people who want nothing more than to be white. You have met the corporate versions of these a**holes.
These people will track 'white' no matter what. They're to be avoided like the plague: white people with truly good intentions who are truly anti-racist are much better choices than these 'actors.'
Thanks again...I've dealt with these people for 30 years at work and even more in my family, so I truly sympathize!
