There has been prohibited language for as long as humans have talked, and the result of it is nearly always a proliferation of euphemism. People who want to talk about something on the naughty list will simply coin different phrases, and sometimes, those neologisms will actually have more nuance and variety than the old banned words. You cite one prime example of this in your post.
That’s the thing about ideas: they transcend language, and thus language shifts around them. The ideas themselves are much harder to suppress than the mere words used to express them.
