Note how they always enshrine gender in biology, but then make all kinds of non-biological statements about what gender is.

"XX is woman"/"Large gametes is woman"/"can conceive is woman"

And then they'll say

"Women aren't as aggressive", "women are more emotional", "women like being in the home more", "those are women's clothes", etc.

The only reason it's so important for it to be biological is because of how it punishes gender non-conformity and makes the lives of trans people hell. Like it isn't ideologically consistent and they know that. They just don't care. If it was just about genitals or chromosomes, then why is it that gender dictates all these social things about us? The only reason to root gender in how you were born is to ensure gender roles are as rigid and immutable as possible.

Confidently incorrect is the default with these people. I spend most of my time with family aggressively correcting misinformation about my field and related ones. They will die earlier thinking they know more because of Youtube. Getting them to stop taking bad health advice and mystery joint injections from a fucking chiropractor is the latest battle.

One time a woman told me that my lack of a second X Chromosome meant I would "always be a man"

So I gaslit her into thinking her husband had klinefelters.

I hate how Republicans think transphobia is science

"Yeah but science can be proven wrong an change over time, while my beliefs and biases are forever!"

I hope this criticism is valid :

There is a "people think they are better than average" rule, rather than whatever Dunning-Kreuger suggested.

Wait until they learn about XXY, XYY, and XO individuals.

Can I get a T shirt that says “I have Dunning-Krueger and your Phd looks cute”? I just have a lot of BS to share and I don’t want to be sorry about it.

While this is very funny, and definitely representative of a sort of ignorance/arrogance commonly found in ideologues - I recently learned that most people talking about the effect have, in fact, been Dunning-Krugering themselves.

Insightful video on the topic.

What most people expect the effect to look like:

What the actual results were:

You know how a bunch of villains are Dr. So-and-So? I bet it's dealing with morons talking about your area of expertise that leads to one's villain era.
