We have somewhat similar in Canada, not as dreadful as USA, but still what you would say anti-knowledge.

I saw this in gradeschool, kids actually trying to learn and better themselves were bullies and labeled brown-noser losers.

At University the Uni newspaper editors would dumb down articles purposely, since they thought the general reader may not understand the topic fully ( which defeats the purpose of knowledge articles ).

And random times. Some guy talking about making his tent lines taut, and the rest laughing saying you mean tight. And him saying , no tension on a rope or cable is taut, tight is for fastening bolts, etc. Then everyone being "yeah whatever idiot"

And overseas teenage relatives visiting , knowing 4-5 languages, and saying "Sorry, my English is not the best" and me trying to explain it is way better than half of the coworkers I have who only speak English. And then trying to explain to a teenager that these full grown adults have no desire to learn correct terms, grammar, spelling or punctuation.

Trying to read my wife's family's facebook posts is like a course in stroke cryptography.

Anti-intellectualism seems to be resurgent in recent years. Its the worst I've seen since the Bush 2 era, and it's all pevasive.
