The fault is way beyond whether the assertion is truthful or not. The assertions aren't even syntactically meaningful.
They have broken the human brain, they have upset human cognition by removing language from any contextual reality.
They have inverted the Turing test for artificial intelligence. What comes out of the human mouth is now indistinguishable from random sentences generated by a computer.
It's been a long time since I did any reading in Linguistic Theory, but this is actually a really good observation.
I've lost track of where Noam Chomsky falls on this divide, but some researches think that the inherent neurological structure of our brain pre-disposes us to have language with certain inalienable characteristics. Other researchers think that the dynamic evolution of language over time has re-shaped basic human cognition and thinking patterns. Or perhaps a combination.
I think the Left gave up on "Truth" and "Objective reality". They seem to believe that things just are whatever they want them to be. This goes against Aristotle's idea on Identity which Ayn Rand constantly referenced: "A is A". For the Left, "A is A and also B and sometimes it's C as well, depending on how we feel. And Eleventy-thirty is my favorite number."
The Left has made language meaningless and now they can't think straight. This is probably an actual psychological problem for many people right now. No joke. This could be a serious mental health issue. For millions.
Projection here too. Admitting they are under mind control, but projecting the controller onto their enemy. I have seen evidence that language itself can control these sociopaths. They are very easy to manipulate. So who is controlling them ? Where is that church lady when you need her....lol
