In and of itself, the allegation that the only reason people might want to do some sort of show of solidarity or support for a historical marginalized community is because it’s being pushed by non-specific monied interests for non-specific reasons is transphobic.
They are not saying that it’s the only reason, they are pointing out something and it happens to be true, they are pointing it out because someone else mentioned the argument.
I’d argue it’s because there’s been a massive transphobic pushback against civil rights by religious fundamentalists and conservative groups.
This had me to read his original comment again and i have to admit i misunderstood something, i thought he implies that the bourgeoisie were doing both: promoting it and pushing transphobia. (which seem what they are doing)
I guess his reply sounds kinda cold but i still feel like you a bunch of old men yelling at clouds, if you care about the topic and are concerned about it you should go spend your time and resources against actual transphobes and not chasing after people comments like the inquisition.
