I'm white and totally against white racism, as well as every other kind of racism.
I don't know which "liberal group" at which university you're talking about. but if somebody is really proposing to do this, I think it's really stupid and I don't support the idea.
In my experience, white people like me ALREADY spend too damned much time "separating ourselves from the rest." This proposal - IF it's real, and not just fake news by some white racist Troll -- would make the problem of white racism worse. And to hell with that.
To be fair, I think a lot of impractical ideas like this one actually are based on a good notion -- that of demonstrating for white Americans just how much racist BS many other people in our society experience in the course of their every day lives.
I've lived in a mixed-race neighborhood of Washington DC for about 35 years now, and I know from experience that I get treated better by the local cops and store owners than most of my black and Latino / Latina and/or Asian-American neighbors.
There really is a surprising amount of "institutional" racism still remaining in our society, and many white people I know just aren't aware of it. We mostly don't get affected by it personally, and it's hard for us to imagine the lives of black / Hispanic / Asian neighbors who live with it all the time.
I think it's also true that many of us who believe in racial equality and racial justice are still more racist in our thinking and our habits than we want to admit. I know that I am. This is not because I or most other white people are "evil," but because we've all grown up in a basically racist culture. It's almost as if there's racism in the water supply, and many white and nonwhite people just can't escape from it.
Sometimes, too, well-meaning efforts to reform the culture to make it less racist have the opposite effect, because they make it so hard for Americans in general to stop thinking about race & racial conflict all the time. This affects everyone's brain in some negative ways, IMO. Even when the intention may have been good.
