I recently noticed a post from a blahaj user whose profile was styled after Celeste from Madeleine. She does trans stuff and posts quite a bit, including to a sub¹ called "femcelmemes".
I've seem the word more than a few times in the past year, and I thought it meant "female incel".²
However, the sub in question just seems to post girly stuff and be accepting to all feminine energents "where anybody can post memes that fit the vibe." So what the hell is this vibe? I don't see any incel-adjacent stuff except maybe some facetious self-deprecation, but do you have to get incel vibes to do that?
¹ Until we can truly standardize what we call them: magazines, communities (Lemmy, please pick a better name. This is too vague.), forums, hashtags, etc..., I'm calling them something we can all understand.
² Thinking about the etymology of "incel", "femcel" should actually be "female celibate", but who in the sam hill cares.
That's funny, it never really annoyed me when people called reddit subs channels. I suppose differentiation is not particularly important in my mind. Neither is conformity, so it doesn't really bother me that much when people use the lingo they prefer, so long as their meaning is clear.
I don't see it as being any big problem, in general. I'm not personally bothered by community, either, it's the term I personally use. I do acknowledge that some people don't seem to like it though, and that too does not bother me.
One problem with your accent example is local cultures were never chosen, they evolved slowly over many years. Lemmy was engineered from the ground up, very recently. Someone chose these specific things, so you're not adapting to some long storied culture, you're adapting to an arbitrary choice some dude made a few years ago. I think this is partly why people feel more comfortable criticising it, where they wouldn't if it were something like a local dialect.
