I'm worried about all this as well, but then I remember how awful (in different ways) 1980s student politics was and then I think current students are not worse, or more stupid, they just have their own particular ways of being solipsistic self-deluding gits.
My (fashionable) university was particularly polarised, right vs left. The right was gleefully, horribly racist, sexist/misogynist, triumphalist in the Thatcher vein, only worse, and openly happy to denigrate anyone unconventional, especially gay people, and demonise the poor.
The left was very male-dominated, oppressively doctrinaire, inflexible, wedded to ideas of equality and multiculturalism but wholly unwilling in practice to make the slightest compromise or give up privilege to bring these things about, had a tendency to dictate to minorities and women about how they ought to be and what they ought to want, and was addicted to name-calling and shaming.
And before anyone jumps in to say 'No change there', it really was worse than today. Viciously personal and uncompromising. I remember a posh leftie having 'class traitor' screamed at him when he spoke at a hustings, and I was publicly upbraided on campus because as a black student I should have gone on an anti-apartheid march and hadn't.
In fact, between the racism and the shaming, there was hardly any space for black individuality and autonomy at all. We used to huddle in a little group (there were VERY few of us) and laugh about it all, so as not to cry.
