While I agree with you, that is very much the game that is being played here. We have competing world views and one way to help a world view dominate is to play a linguistic war. That was the point of Newspeak in 1984 (https://en.wikipedia.org/wiki/Newspeak). If you control the language such that competing ideas are instantly taboo just by the words required to describe them you can stop people from promulgating those ideas. So you gain ground without ever having to debate the new ideas.

This has happened in many countries when one religion dominated. Western society was starting to get to the point where it taboos were being shed and ideas could win based on their merit. Sadly we're regressing back to a society controlled by dogma rather than an open exchange of ideas. I suspect this is the normal state of human societies, we fluctuate between open and closed societies.
