Yes, I have really noticed this too.
There's a not very active thread in AIBU, and I've seen other similar discussions, about the priest that was let go over a sermond saying it is ok to disagree with things and important to think critically and be respectful of others views.
If you just look at the responses in these discussions - people have no idea why those things are important.
They have no idea that it is possible to discuss these ideas and engage with them intellectually as the onl reason they think abnyone might disagree is bigotry.
They have no idea that there are, or even could be good reasons to think critically about the mainstream view on such issues. (For example, is it possible, at all, to have laws that differentiate between people based on their biological sex, and under what conditions if so, and what might be the consequences of saying that it's not possible.) Like, not on the radar.
And they seem completely unaware that in recent history many ideas they hold as non-negotiable were only challenged because of people who were willing to go against the accepted view. Or that within the span of history further back that there have been completely different ways of framing the discussion which lead to very different considerations, and that this might be worth knowing something about.
I work in schools, I have really noticed a complete lack of real teaching on critical thinking. They talk about it a lot, but what they mean is teaching the right view on various topics and a pseudo-marxist, and frankly inaccurate, view of history. And making sure thy don't have one idea in their little minds that might spark a question.
