That kind of language policing is ridiculous. The words mean what they mean. If there is some taboo around a word like Marxism or feminism or islamism, that doesn't mean we need new words, it means there is resistance to the ideas. Over time the words depoliticize slightly and can be used freely again.

Giving in to people who are trying to cloud the meaning of words is the linguistic equivalent to negotiating with highjackers. You can do it, but you just make the job easier for the next highjacker.

I know it's a scary moment, where it feels like words have lost their meaning and insanity reigns, but that's just the zeitgeist. Words still mean things and that still had power.
