Not quite. I know a few white folks who March with Black Lives Matter. They are either social workers, social justice warriors, or just run of the mill libs, or whine there are several in NYC.
The first you mention are “poverty profiteers” (like public school teachers in the ‘hood); they are paid to pretend to care. The balance, if they live in NYC, are basically hostages; even in “nice parts”, the animals are a subway ride away.
