Asklemmy

Being poor and idolizing the rich.

Bigotry and prejudice. Not necessarily uneducated, but certainly poorly educated.

Being proud of not knowing things, and having no desire to change that.

Thinking that someone without a formal education is somehow beneath you.

Not being able to entertain ideas. "What would the world be like with 100% renewable energy?" "Would basic healthcare for every person help our country?"

I tried to explain the 4 day work week to someone that gets paid by the hour. You make the same money but work 4 days a week instead of 5. Insisted he got paid less. Had to explain like a Bingo card with a Free Space, 1 day he is paid even if he stays home.

Not trusting in science.

Edit: Since there are many comments, I would like to clarify my statement. I meant that you should rather trust scientists, that the earth is round / that there is a human-made climate change, etc. and not listen to some random internet guy, that claims these things are false although he has made no scientific tests or he has no scientific background. I know that there are paradigm shifts in science and sometimes old ideas are proven to be wrong. But those shifts happen through other scientific experiments/thoughts. As long as > 99 % of all scientists think that something is true, you should rather trust them then any conspiracy theorist...

People who litter. Throw their rubbish out the window of the car. Or who throw rubbish in public, like into drains or sidewalks.

It’s in the mentality, and I say the lack of education is the reason for it.

It’s sad to see the people of my country do this, and to see it with your own eyes.

I see this in a lot of places I do work:

Toolboxes covered in union stickers, AND Trump stickers...

Being proud of not owning books

Parents feeding their baby cola in bottles and smoking while pregnant are two things that usually cause me to make assumptions

Being a baby. What do they even know?

taking Ayn Rand's work seriously. five seconds of critical thought and her entire philosophy comes crashing down

Being a republican. Sure there are some educated grifters who decide to label themselves as republican, but your average republican voter is a mouth-breathing fucking idiot.

They think opinions are facts.

religion and the belief in the supernatural/paranormal. also the belief in conspiracy theories.

Black/white thinking. Everything is either bad or good, the problem or the solution.

Reckless driving, speeding, having a loud car, having a lifted pickup truck.

Refusing to accept that they are wrong.

Racism.

"Let's go Brandon!" Bumper stickers.

"Whataboutism", or if you are unfamiliar with the term:

"The act or practice of responding to an accusation of wrongdoing by claiming that an offense committed by another is similar or worse"

People that use this mechanism are "poorly educated" and unable to hold a conversation and they should just be mocked by whatabouting even harder, so they can maybe understand that they're dumb and that's not how you should debate.

Example of the last argument I had recently with my dumb c*nt father:

• Me: You shouldn't idolize that politician, he evaded literally billions in taxes and that befalls on citizens like you
• Dumb c*nt father: Yeah? And what about that other politician?
• Me: What about the disappearing middle class?!
• D.C.F.: What...?
• Me: WHAT ABOUT THE BEES!?!

Anti vaxxers

Associating with arbitrary groups, such as football fans, nationalists, wearing certain clothing brands

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.

Using terms like 'u', 'ur', etc when writing. No one charges by the letter, it's simply lazy.

Cigarettes

Ironically, defending arguments using scientific studies and experiments, but not being able to think critically about the methodology used or what the results mean. Too often people will cite scientific literature based off the title and MAYBE skim it. Trying to have a discussion with them will usually result in them calling you anti-science.

A good example is the pseudo-scientific belief common within incel circles that women can store and absorb dna from past sexual partners and that their children can then have more than one genetic father (an excuse to shame sexually active women while fear mongering about cuckoldry). If you track down the source the study actually explicitly explains exactly why this isn't the case.

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

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

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.

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

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

Wearing camo and American flag shit in public. Honestly just having American flags on anything now pretty much is the same as that read hat

Breaks for brakes, loose for lose.

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