What is hilarious is that in these very forums certain words or phrases that are allowed in the general public are verboten here.
F-bombs are OK, but don't dare use a word or phrase that offends the political Left. Those are the new "swear words".
There will always be words considered "profane". They will just change based upon who is controlling the narrative.
Though I don't agree on the left vs right thing and I tend not to get into that too much anyway ( every group of every type made up of people has some form of controlled elitism, essentially no one's side shit doesn't stink ) and for the record I happen to be very left on most things.
I do agree with you in general though. Different words offend different types of people differently. I see it as only natural that groups of certain people who run a social group may, for the sake of their members be more conscious of certain phrases or words.
Personally I find that to be a very reasonable point of view. This site for example may be a kinda social fan club but it does have customers and their sensibilities should matter be them this way or that. I haven't been around here too long so I don't know what those sensibilities are.
What I'm trying to say is that the idea that fuck is a-ok but other words that aren't classically profane, are not ok depending on the group is normal and I'd say even a good thing. Else you have a ruling or enforcing body without their finger on the pulse of its people, and that's just weird.
