By 'liberal,' do you mean 'basic human decency?' Because it seems like people use the 'liberal' label as a pejorative against any person or movement that works to grant equal access to minority & marginalized communities.
Your argument here shows a fundamental misunderstanding of how racism works in the U.S.
I truly wish more of my fellow white folks would come on over to the right side of history. Take some time to read, listen & learn about systemic racism in America - there are PLENTY of great articles right here on Medium that discuss it in great detail.
Saying that Kaepernick Publishing's "own words" makes them a "racist" organization because they're only going to publish articles from Blacks? That's not how racism works in this country.
As white people in America, we are not oppressed or excluded in general. We can look around and see authentic representation basically everywhere: people who look just like us, usually, speaking as voices of authority, power, or influence.
At no time has our entire race been oppressed in this country. Indeed, we have been the only race to achieve *and* maintain power across all systems - educational, professional, political, and so on. We are not the minority here.
But we have certainly benefitted from these same systems that oppress minorities in ways we can't see (white privilege, by design, shields us from awareness). Whether we realize it or not, we have benefitted from these same systems that preserve the white race in America as the "default norm." And we have certainly benefitted from standing on the shoulders of giants who were black, and more often than not, uncredited.
You still have all the writing opportunities you did before. So what's really the issue here - did you really, legitimately want to contribute something to a publication that focuses on black culture? Do you feel an opportunity is being taken away from you? (By the way, most of the publications on Medium focus on white culture, except Zora, and a few others).
I don't say any of this out of disrespect. Just fatigue.
