No. As a careful reading of the previous comments and of my work more generally will show - I am in support of your second amendment rights. You can carry a gun and you can set up communities if you wish - as a left-wing liberal, I don't have a problem with this - if a new chapter of the Black Panthers springs up, then I'm all for it - because, in the nicest possible way, it's socialism the way it should be done. It helped poor people and did some excellent work nobody else was doing.
However, the likely outcome of setting up and subsequently then arming communities of solely BIPOC will be Apartheid. That's it. See the definition:
Apartheid
a policy or system of segregation or discrimination on grounds of race.
Whether that's done by you with guns or white politicians through political means, the outcome is the same. If you think that's the way to go then great. Saying I don't think this is a good idea because it plays INTO the concepts of White Supremacy, doesn't make me a white supremacist.
Put simply, your goal of 'removing black people from a shared society' and the white supremacist goal of 'removing black people from a shared society' are entirely aligned. The question you need to grapple with - is 'what happens to a small state within a larger state' when their political and social interests diverge. Ukraine should give you some idea.
That's when you'll see the real nasty fangs and jaws of White Supremacy done by actual violent racists. Consistently accusing everyone who disagrees with your political viewpoint of being a supremacist moves the discourse nowhere. You seem like a smart man, what's your end goal here? What is it that you actually want to achieve? A civil war? Racial segregation?
