I've never been to actual communes but I've been to similar situations. At my old uni there was this thing, like student housing but different from the regular student housing. Those houses are effectively managed by the students who live there so they have different systems and you have to be invited to live there. I went to a couple of the left-leaning ones and they were pretty gross. One was especially bad, it attracted an even larger amount of "bathing is bougie" types. For example, there was this white guy with dreads and I'm sure you can see where this is going, his dreads were 100% disgusting, he always seemed to wear the same pants, he wore sandals and you could always see black grime under his toe nails, and he always smelled like fish for some reason I'd rather not know. I had a classmate who lived there (we were never actually friends and she later turned out to be really into shit-talking people) and invited me over for dinner, I don't know how I managed to be polite and eat because their kitchen smelled like actual garbage. Also, somehow in these houses they could paint murals but had mold growing on the walls and somehow couldn't fix that. SHUDDERING FOREVER.

In my case I don't think it's just being burgeois because I have reasons! One is obviously my OCD. The other is cultural and the way I was raised. My father is a very gross person and showered every day, now imagine those of us who aren't gross.

I also don't think hygiene is burgeois, it's annoying people looking for an excuse to be disgusting while trying to claim leftist cred.
