In my neighborhood, we have several black families as well as other races. The only BLM sign I ever saw in my area was in front of a white liberal’s house.
In my very rural “neighborhood”, we mostly have moose families. :-)
I do visit civilization from time to time, and that is where I saw the sign.
Of course they were white liberals, but I would bet their not so liberal neighbors are probably having discussions about what to do about the sign.
These folks paid big bucks to live in privacy in their very upscale all white neighborhood and they do not like to draw _any_ attention to themselves. :-)
