This is in the US/UK.
The problem is, these students are not coming here to learn how we're all equal, they're paying for a degree that proves they're very much not equal to about a billion people back home (compare the median wage in China with the cost of a one-year MSc in the UK for example).
That's also why most of our Covid-19 planning is around how do we deal with the income loss if 50% fewer international students enrol next year, the options seem to be government bailout or bust.
So there may be an unspoken rule in some places that you don't criticise the latest theories on diversity, but there's an even more unspoken rule that you don't publicly apply them to the situation in Tibet or Urumqi.
It will be extremely interesting to see how these two pressures interact over the coming decade.
New York City has (or had?) an active effort in place to cancel/dismantle "gifted" programs in primary and secondary education. Here's the PDF released by their committed last August: https://docs.wixstatic.com/ugd/1c478c_f14e1d13df45444c883bbf... . There are lots of other examples of this phenomenon around the country... I doubt I need to come up with more examples now.
Notably, the University of Chicago came firmly down on the side of free inquiry: http://provost.uchicago.edu/sites/default/files/documents/re...
An excellent, charitable, clear-minded discussion on critical theory in general: https://youtu.be/p6DnHxuuXI4
Here's a good introduction to many of the practical, everyday consequences of CRT/I's influence in American culture. It's an interview with Peter Boghossian and James Lindsay (this is part 1, and I think there are 3 or 4 parts in total): https://youtu.be/YDFL3xwEEG8
-- that last one in particular, if you watch the whole thing, is chock full of great examples.
Hope that's helpful. That's all I was able to find in the time I had.
What you write sounds plausible, but it also mirrors a lot of what we hear from the right that is at times overstated.
I'd love to hear a set of sober examples- I don't have any connection to early education anymore and I'm really curious.
