Isn't a rule that says people of one skin color are not allowed to have a voice in and of itself such a power structure?
Look at it like kids on a playground. If there are a bunch of bullies picking on little kids, and you tell the bullies that for an hour a day, they aren't allowed to go near the little kids, is that a power structure set up to dominate the bullies? No; the little kids just needed a break! The bullies still have their power the rest of the time (and you haven't actually taken away anything from the bullies but their ability to bully; they can go about their lives as normal everywhere else)
Everyone keeps getting hung up on "there's a rule about skin color!" Yeah, there is, as a response to constant systemic racism forcing marginalized people to find a safe space. Turns out the world is complex.
Indeed it is.
Can you make a solid case that your claim that "constant systemic racism forcing marginalized people to find a safe space" is as conclusively true in the real world as your simplistic imaginary playground example?
If your case is indeed valid, facts should suffice should they not?
The interesting thing about such interactions is I suspect your mind remains as ever confident as before....you can't articulate a logical defense of your beliefs, yet this fact has absolutely no bearing on the strength of the belief.
