>>2282369again: you keep saying "support" as though there's any actual material support. it is not a leopards ate my face moment to laugh when it rains on your enemies, and to be mad when it rains on your friends. we do not live in a democracy, and me saying "i support x" does not actually mean anything. support must be material: a support beam holds up a building. me saying "i support the building being up!" does nothing.
your analysis is also very simplistic: contemporary establishment-liberal idpol (which is actually giving way to open reaction, but whatever) was a response to pressure
from below. all the tedious little identity groups exist, have actual problems, and were beginning to organize and become conscious of them.
in these circumstances, the people in power did what they do best: channel that pressure from below into harmless avenues. #landback is expensive, but a land acknowledgement is cheap. fixing biased hiring practices is difficult and expensive, but hiring a grifter to give you unconscious bias training is cheap. transgender healthcare isn't actually that expensive, but pronoun circles are even cheaper. take a small, middle class segment of the group and elevate it, then direct the rest into endless discourse.
i suspect you want a future in which we just put all the tedious identity group whining behind us and go back to 1975 where you can just have a bunch of lads hold a red flag. it isn't happening, if there is a future for the left it includes liberating all of the unaesthetic identity groups from the cul-de-sac they've been misdirected down.
(which sadly, again, means communists must engage with people they find annoying.)
