It's like a hard to believe science fiction society where you're allowed to talk about anything except exploding hippopotami, because the king's mother finds them gross and would rather everyone just talk about beheadings like good little children.
This is degenerating quickly. I may expand this into a real essay when I have time.
I make a slight exception for swear words with a religious background. At least they honestly believe that their children will go to hell if they ``take the lord's name in vain'' (in quotes because I'm not 100% sure what actually constitutes in vain). This is inconsistent of me and I haven't quite resolved it in my head yet.
