I for sure see a lot of that going in the genderism debate, in the plain astonishment some express when GC women disagree that TWAW, as if the very idea that that is NOT a fact as we define facts and is a matter of opinion such that reasonable people can disagree is utterly beyond their comprehension.
Yes, at least to some extent I think this is a failure of understanding. People I know who say TWAW consider that it really is a fact. All the authorities - the doctors, the lobby organisations, political types who aren't bigots, all agree. Science tells them that sex and gender are complicated, they know because they read it in Scientific American, national Geographic, and Psychology Today. People who say otherwise are scientifically illiterate, probably also anti-vaxxers or climate change denialists. People who think all the real science is fake news.
My daily interest and life is in education, formerly more at the university level but these days focused on my own kids and also the school I work at, which is elementary kids in a somewhat deprived area. I've watched carefully how my kids when they went to school, their friends, and my stedents are being educated. There is alot of discussion about teaching critical thought, but little or no understanding of what is necessary to get the kids there. There is no real teaching of logic. There is no teaching about the assumptions or history of their own thought system so they can be self-aware in their thinking. There is very little content in terms of history or politics so the kids don't really know anything, they can't see patterns and they have little sense of how things change or develop over time, and little concrete political knowledge. (From what I have seen this is better in the UK than it is here in Canada.)
When they do teach history or social studies, making sure they think critically means setting up the teaching so they inevitably come to the "right" conclusions. And quite a lot of time is given over to books and films and speakers coming in to present on various social issues.
There really is no chance for these kids to learn real critical thinking.
