If you actually talk to any people, you’ll find a lot who are upset about the behavior of criminal and otherwise antisocial individuals, true.
But to focus on being upset with those individuals specifically for “pushing the movement backwards”, or “sabotaging progress”, etc., is an attempt to duck responsibility on the part of mainstream majority culture.
Individual black criminals, and even gangs of black criminals, as reprehensible as their behavior may be, are not doing anywhere near as much to sabotage progress on racial justice and equality as white racists are still doing.
Sure, just like in any other community. But, again, if we’re focusing on these “subcultures” as the most salient obstacle to overcoming persistent homophobia in American society, we’re not being honest about the problem. The people who are doing by far the most “more harm than good” to LGBTQ people are not any subculture of LGBTQ people themselves.
If we disapprove of the behavior of any particular “subculture” in any group, let’s criticize them for the specific things we think they’re doing wrong, not in general for “holding their people back”.
That’s just a deflection (albeit often an unconscious one) to allow mainstream culture to shift the chief responsibility for persistent discrimination onto the discriminated-against group itself, in the guise of some “subset” of it.
“If you people would only fix your ‘subset’, you wouldn’t be pushing your movement backward so much.”
“I know it isn’t bigoted to say this, because if you talk to a lot of those people you’ll find that they don’t approve of that ‘subset’ either.”
No, I don’t think I’m the one whose lack of “nuance” is causing your problems here.
