Anyone supporting someone only on the basis of their (gender) identity is laughable, no matter their orientation. I can't stand woke "feminists" either, and although I can appreciate some of their concerns, I'll gladly push back against anything I think is nonsensical.
40% of people in entertainment are black and 20% are gay? Which stats are you using here?
GLAAD report from 2019 have LGBT at 10% and black people at 22%. That's a few percentages over the distribution of the target demographics, but not wildly so (about 8% of millenniels identify as LGBT and about 16% are black). Hispanics are underrepresentated though:

On the flipside, it seems like more millennials and GenZ's are growing "uncomfortable" with the LGBT. So the pendulum will probably swing back, and hopefully normalize, in the next few years:
