It's because it's an ideological cudgel. It's non-standard, strange to the vast majority, and feels extremely dangerous to those who are versed in history. If words are violence... the sky is the limit in terms of restrictions to speech.

It's nonstandard and confusing and shall always remain as such.

If you think it's confusing, then the best I can say is that you have a _lot_ of reading to catch up on. But here is at least a very abbreviated primer on terminology to help alleviate your confusion https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2652990/

No thanks, I'll just stick with the normal definitions of words rather than do "a _lot_ of reading" to learn what the latest ideological contortions are.
