Racism is still a thing, no matter how much we wish it weren't. It's here, and as always -- since conservatives are pretty serious about that "inalienable rights" stuff -- its coming from politically Leftist movements.
Here's left-leaning British publication The Guardian explaining how blacks excluding whites from a space is progress, not evil:
In contrast to Nyansapo, self-organised “white spaces” -- think far-right groups -- are almost always layered with prejudice and the flawed notion of ethnic superiority. They are made in opposition to diversity and multiculturalism -- and that, coupled with the uniquely powerful positions white people hold in society, is why they are unacceptable and reek of segregation. Black-only spaces rarely exist for the same purpose; instead they are founded on the basis of the true lived experiences of struggle. By denying white people entry to them we are not reflecting existing power structures, we are trying to subvert them.This is certainly the case for the Nyansapo festival, which is organised by Mwasi, a black feminist organisation formed in 2014 by those who felt underrepresented in the French anti-racist scene. The festival will be the first one Mwasi has held, and apparently the first black feminist festival in France. Its aim is to create safe spaces with the opportunity to discuss black feminism, anti-racism, Islamophobia, homophobia, transphobia and other forms of systemic oppression.
In short, judging another by skin color rather than character can be just dandy depending on the motivation.
Being from the Deep South, the legacy of segregation is everywhere. Back then, whites had their places and expected "coloreds" to keep to their places. Activists now forming minority-only spaces are doing nothing more than resurrecting segregation's legacy. They're seeking to reduce social interaction between the races until ... well, they don't say if there's an endpoint.
Discounting someone based on DNA is evil.
Calling these areas "safe spaces" is abominable. If you believe that a white person being in your presence means you are no longer safe, than you believe white DNA is inherently dangerous. You are engaging in evil.
You deserve the same scorn the Jim Crow Democrats deserved.
