Being poor or lower middle class and voting for right wing/conservatives. You essentially give away your hard earned money and give it to ultra rich and worsen the quality of your life.. usually because the right wing scares people to be afraid of other people and new phenomena.

Believing the earth is flat

I’ll take “poorly educated” over “educated and unwilling to learn or grow.”

Referencing the Dunning-Kruger effect in casual contexts. Most people who refer to it, have not really read about it enough to be qualified to use it.

Any reference to "common sense", which really means "what I believe". Violating it is used as a universal rebuttal for any intellectually sophisticated argument.

MAGA Hats. Those people are dumb by choice. And that's less forgivable than people who just don't know any better.

I'm going to interpret poorly educated as badly educated as opposed to just not.

Imo the best sign of someone who has been brought up wrong is a total inability to tell the difference between what is legal and what is moral. Don't smoke weed because its illegal. Those homeless people shouldn't have slept outside if they didn't want to be arrested. Nazis should be allowed to march in the ghetto. I've heard all of those from people that have been raised wrong. They don't have any capacity for care, and they're basically just robots fullfilling whatever function they've been told is expected of them. Their hobby is watching tv. They have a wife that they never talk to.

People who are proud about their lack of knowledge on a topic as if that somehow means that they were not programmed prior to the encounter.

Getting on an unsafe submarine

Well we definitely have a lot of reddit in this thread. Reminds me why I looked for alternatives in the first place.

Breaks for brakes, loose for lose.

Not learning from history.

Using an apostrophe in plurals. Don't know why but this one drives me insane.

Also they're/there/their and you're/your

Listening to loud music without giving a shit about the neighbours.

It depends on how you interpret "educated". If including things that aren't learned on school: I think that fallacies, rushed certainties and decontextualisation scream "this individual was so poorly educated that they never learned how to think."

I think that everything else can be derived from the above, shitty moral premises, or a mix of both.

Insisting things like tax returns or household maintenance should be taught in school.

The goal of Education is not to train you to fit into the system you happen to grow up in, but should provide the foundation (litaracy, STEM, art …) and awaken the curiosity in yourself to become lifelong learner. That will develop society, and not a bunch of drones doing their tax returns and changing tires every season.

Confusing THEN and THAN. Credibility immediately drops.

Being intolerant of those who don't think like you do.

Yo momma

People who think their dialect or language style is grammatically correct and others are wrong, because they don't personally known the grammar rules of any other dialect or language. They don't understand that language is alive and evolving and that the purpose of language is communication.

Per say is a giant pet peeve of mine.

Confuses to, two and too.

Also their, there and they're

Using "I" as the object instead of the subject, like saying "The waiter brought drinks to my friend and I."
