My personal philosophy for most topics is to find out what the extremes are, then look at what the middle between these would be, and then call that the ideal.
On Reddit, that philosophy is enough to be called "racist" and "Nazi". Trying to start a proper discussion to (in-)validate any of my - in my opinion - rational points was met with "I don't talk to Nazis!" several times. Mind you, I never even talked about race or anything similar and most times not even about culture. I basically formulated my starting points, added some facts, and was ready to discuss. There were very few discussions that really took place and I have even changed my opinion on several topics based on these discussions. But in the last few years, even these few discussions became less and less. I can only remember one discussion in the last two years that I had with a left-wing person (a teacher from Africa) and I only got this far because our kids were playing with each other. Based on what she told me, I am pretty sure that I would not have the chance for that discussion under other circumstances. She even thanked me for that conversation and told me, that she could not remember the last time that she could talk so open to anyone. I don't know if she realized that she told me how she categorized every negative feedback about her as "racist" half an hour earlier. Strangely, the more to the left a person is leaning, the less they like to discuss nowadays. I find that very strange and also not helpful to their case. If I have two parties where one of them likes to discuss and argue, while the other one directly calls anyone with a slightly different opinion a swear-word, I tend to sympathize more with the party that likes to speak with me. I've yet to encounter a really right-wing extremist that is actually racist. I know that they exist, and I have a friend who was in one of these groups when he was young, but I never had anyone tell me directly that they find any specific ethnicity inferior to others or something in that regard. Well, except for members of a certain religion, but I don't want to start that topic here.
Btw., I am German, and I associate the word "Nazi" with war, racism, and industrial-scale mass murder. But today it is enough to say "I don't like how the immigration into Europe is handled, and I think we should reduce the amount of illegal immigration" to be called a racist and even a Nazi. Ffs, I've seen people in high ranks calling people "racist" because their products were criticized. It had nothing to do with race or anything like that, only with the quality of the product, but they still throw that word around as if everything was just based on race. And if people say that everything and everybody is racist, they at some point start believing that themselves.
Nowadays, you really have to be careful if you criticize anyone's work if they are part of any minority. What's even more ridiculous, most times it's not even the person themselves, but some other person who has their "everyone is racist" opinion, and they will start attacking everyone who dares to critique anyone belonging to any kind of minority. That leads to "toxic positivity", where no-one dares to call out any BS. And that leads to bad products being created. Just look at some of the films and games that have been produced in the last few years. Concord is a good example of something that is the result of this "woke" culture.
This is bad in so many ways. If you hire people by how good they fit into their role, the heritage of the applicant must not be a factor. If the pool of applications does not fit the overall demographic, that is not the fault of the recruiting company. If a company obviously discriminates against anyone, they should be held accountable. That is what I call the balanced solution.
But forcing them to hire specific percentages of certain demographics is contra-productive. Now you don't have the best person for the job, if their ethnicity, sexuality or whatever doesn't also align with the current requirements. This might lead to very bad results. You want your brain-surgeon to be good at his job, and not just the only one that had the right skin tone in that hiring session. And even if they are good or even the best choice, others in the company don't know that, and they might categorize them a "DEI-hire" anyway. That only creates further resentments.
The greatest success I have seen in the fight against racism was not seeing color. We should be color-blind and treat everyone equally. For a time, that worked great. Today, the heritage, gender, color of skin and even sexuality are things that have to be acknowledged, recognized and valued. I've only seen bad results coming out of this and nothing positive.
Oh, and about the part of the professors making their students "feel uncomfortable"; Of course, if a professor says something like "Women belong in the kitchen anyway", or any really sexist or racist stuff, that behavior is not okay, and they should face consequences for that. Only making someone "feel uncomfortable" is not enough, though. To learn, you have to be told if you are wrong. Feedback can't just be positive, and it doesn't help anyone to be wrapped in cotton candy for their whole education. That's what leads to the aforementioned "toxic positivity".
About my last point, I strongly recommend this podcast. One part dedicated to this is timestamped, but I recommend listening to the whole thing. It's really good and it explains a lot about our behavior. https://youtu.be/R6xbXOp7wDA?si=MCF3hfZxe9NmzJ-b&t=4724
