It's established as "political correctness" and "decency" to cuck in to everything and everyone possible and stick to a language of pseudo-intelligence: Speak as if you're smart and know what you're doing.

Trump doesn't give a fuck, and with that, even though his language is more banal in its unique way, he is way more approachable and relatable to common people (but also to people who appreciate honest characters). He does not present himself as someone morally-intellectual superior passively, even though he likes to boast about how he is superior in many ways (which is fine, he was a candidate about to prove his worth). That makes him transparent in this regard though, he tells it openly, instead of relying on some arrogant, passive form of implication: "I talk smartly, so assume I am smart."

This is also the reason why people who think they are smart (primarily from academia, wasting their time on useless nonsense at tax payer costs) call him dumb (which is ironically stupid). But they also called Jordan B. Peterson the dumb person's smart person. So to them basically everything is dumb that is not sufficiently socialist & authoritarian for them - or at least in support of the agendas of the "intellectual aristocracy." Which means they continually think they are better than all of us - even though they are indoctrinated morons.
