Going to university in the USA these days sounds like an absolutely terrifying prospect, and doesn't sound very promising for the future of the country.
I went back to school to take a couple classes at a public school in a red state. It definitely has changed but it wasn't that bad.
My observations around this:
* Lots more platitudes. Nearly every teacher in the CS department had signs on their doors about being an inclusive zone or standing for social justice. Seems like it would have been easier to just make a big sign that says, "The CS department is inclusive and promotes equity."
* Early in President Trump's tenure they designated an area as a safe-space. This is honestly the first actual safe-space I had run into, despite hearing about them endlessly in culture wars news. I personally don't mind a politics free zone.
* I had to take a mandatory title ix training. It used words I don't normally bump into but have been targets for the right like "trigger warnings" and "microaggressions". I wrote the title ix coordinator (simply because it felt like a waste of time) and asked if I could skip it because I had already done 8 years of college without running afoul of school rules and she told me no.
That was about it. So I'm not sure how endemic the problem is but my anecdata was it's not too much to fret over. My personal sense here is that the media likes to report these stories because they are "man bites dog" stories.
There shouldn’t be any “sensitive” issues in a university context. These “universities” look more like re-education centers than educational institutions.
All those “sensitive” issues are plain ideological ideas and some people want those ideas to prevail by suppressing all conversation around them.
I think the discussion about this already over, i.e. it's now a part of the social contract that we don't question certain things, not because they're true or false but because of social cost of challenging them. For example, we know that the distribution of certain psychological traits in both genders is a bit different, but discussing it - either in the social context or the academia - is more or less a taboo in order to protect the vulnerable, and in part also because of the expectations of desirable traits in today society [0]. For the same reason, nobody in the right mind would organize a study of IQ differences between races, and if someone was stupid enough, their professional life in the academia (and probably beyond) would be finished.
In general, in the West any study of relationships between the aspect of the body (any inherent traits) and the mind/psyche is forbidden. A few years ago the Chinese published their famous study of facial traits of convinced criminals. [1] The result was that there were more variations from the mean among the convicts than the rest of the population. Of course everybody criticized the study as unethical and minority-reportesque.
The only danger I see is that by effectively renouncing to analyze any links between the body and mind we might lose some important insights, and the vulnerable groups could also greatly benefit from discovering these. But the danger that the result of this kind of research will be used against us is not negligible, as the history shows.
It's not actually taboo at all to discuss variation in psychological traits between genders. There are innumerable academic studies of gender differences in all kinds of domains. No-one, to any significant extent, is stopping these papers from being published, or calling for this kind of research to cease. Similarly, there are endless articles about gender differences in mainstream news publications.
What is controversial is using cherry-picked scientific results to tell just-so stories about why the gender distribution in certain fields is imbalanced.
There is a sea of difference between the Chinese paper and the other two you mentioned. The Chinese were very straightforward: can we identify facial traits that are more present in criminals? To a certain degree, they answer positively by saying there is a greater variation in facial traits in criminals than in the rest of the population. Of course there was a lot of criticism of their methodology (to which they answered [0]).
The first article you mentioned describes the bias of eyewitnesses related to stereotyped "criminal look". But the researchers are very clear: "Further research is needed to identify the features that are associated with the criminal stereotype and how they affect lineup decision processes. The specific elements associated with criminal face stereotypes have not yet been identified."
The second article deals with our interpretation of certain traits (which, in this case, are listed) and it's careful not to imply these traits are actually related to criminality. On the contrary: "such evaluations could inappropriately influence decision making in criminal identification lineups. Hence, additional research is needed to discover whether and how people can avoid making evaluations regarding criminality from a person’s facial appearance".
The Chinese paper is almost certainly wrong. A simple explanation for why other people aren't publishing the same claim is that it's both inherently implausible and unsupported by any of the available evidence. You can find plenty of equally kooky and potentially controversial papers published in Western countries. E.g. https://journals.sagepub.com/doi/abs/10.1177/095679761245146... Of course we can play a game where you keep denying that any example I give is exactly parallel to the paper you cited. However, I'm sure that if you do a few Google scholar searches you'll be able to find something that satisfies whatever criteria you have in mind.
Free speech and academic freedom have always been and will always be under threat. It's a constant struggle.
