There are a lot of angles you could analyze from, but I'll share some thoughts of my own. In the West, communism was always going to abandon the working class because the WC had things too good and knew that they had nothing to gain from the bolshies. Enter Lumpenproles. These are theives, beggars, whores, murderers, etc. The lowest of the low, both in traditional society and traditional communism. Marx and Lenin saw them as downtrodden, useful footsoldiers of the revolution, but ultimately needed to be forced to work or be exterminated. Western communism shifted to focus on them in the '60s/'70s. The KGBTQ+ and various resentful browns slot into this nicely, and thus intersectionality is born. Lumpenproles can be basic standard, or can be champagne lumpenproles (think breadtubers). At anyrate, there's a sort of genius to it. Anybody can claim to be a prole now just by saying that they're some variety of queeroid. It's something that was impossible in traditional communism.
