The zeitgeist of it all has heavy roots in post-structuralism but like... baby-brain understanding of post-structuralism (which even at it's most solid has plenty of scope for critique).
The irony of it being post-structuralist is that it is anchored in an obsessive
need for defining and labelling. That's literally what all of it is about. In fact for those who buy into the current dogma there seems to be some sort of untethered existential turmoil that can only be calmed BY excessive labelling, and by rejecting anything that strays from or questions those labels or mantras... which doesn't gel with post-structuralist logic at all.
tl;dr much of it is (literally) inherently illogical but there's an almost mocking defiantly flippant stock-retort that is, essentially, "it doesn't matter if it's illogical you just have to accept it and everything will be fine".
Some homework if anyone is up for it:
