I grew up in Queens NYC in the 80s and 90s under Dinkins and Koch but I trained in Baltimore.
My friend, we're speaking of two different things here. #1 is the disparaging remark you said about rural folks. I needed to correct you since I know from experience that you are wrong and I must speak up when I see this. You don't have the experience. You only have stereotypes which ironically is the thing that BLM is supposedly trying to eliminate. Rural white folks are the last group in the US that are not protected by political correctness and it seems like they are constantly ridiculed and criticized with impunity. They are overall a law-abiding good people and the stereotypes are so often hypocritical. Despite their relative poverty, they don't tend to constantly complain every second about the way things are or try to blame outside circumstances for their lot in life. They don't typically ask for much, mostly don't bother anyone and just want to live their lives. They also tend to frequently volunteer to shed their blood protecting the rest of us so people like you and me can live the privileged life in the 1%.
Issue #2 is the whole black/white thing you chose to bring up. I agree very little with BLM and would be happy to discuss this further with you if you want. It wouldn't be a fair discussion as I would have to argue with one hand behind my back. You can probably mention whatever you'd like from your perspective but I imagine that I must tread very carefully as it wouldn't take much to get me banned from here from mine.
