No, I'm intentionally using it loosely. Much about racism is actually a cultural clash more than anything about race exclusively.
So, POC is yet another term that gets used as a sociopolitical correction that tends to upstage the actual discussion by redefining normal everyday realities.
All people have color, and no one I've ever met in any first person encounter ever considered himself and referred to himself as a person of color. They have all termed themselves either Black, White, Native, Chinese. POC is a PC term reserved for rarified discourse.
In JUB's attempts to discuss race, it invariably returns to a pattern of throwing out all of another's member's posting, attitudes, and friendships, and attempting to force some esoteric concession on a narrow slice of the race discussion. I've posted on JUB in Hot Topics for over seven years, and seen precious little of anything that can be termed hostile to another race. We have thousands of members, and it is truly rare, despite the constant spin on here about it. It exists on here, but the constant witch hunt to find more of it than is here, or to expose some other member is just a gratuitous exercise that fosters paranoia.
It's much like the notion that racism cannot be from a minority against the majority population or ethnic group. Whereas that may be current or accurate in academic redefinition or narrowed use, the dictionary reveals that racism is racism, plain and simple, without the redefinition.
