The answer, typically, is OF COURSE. Big time. It would be well appreciated by most.
That being said, I get where this perception comes from -- there can be, as you call them, outsider social-justice folk who might try to say something weird here:
But I just need to highlight the "outsider" part of that -- if only for non-black folks to understand and to try to pay attention to exactly who you're listening to and getting authority from? I hate to use a phrase like "real Black people" but I'll go with that for now; real Black people tend to be the MOST reasonable, but often under-heard.
I'm reminded of, e.g. police reform; I understand that it's incredibly important and necessary. Which is why phrases/ideas like "Abolish the police" and "ACAB" are deeply unhelpful.
(and as always, I am only one Black person, nothing I say here should be taken as gospel for everyone, I could be wrong)
