I also could not have any less respect for Rutgers as institution. I know they fired him but the fact he was given a job to teach people at the expense of taxpayers and student loan debt puts their degree below a sham online university.
I find it sort of amazing. I went to a really well known college with an excellent reputation. The joke was always that it was also the most liberal in the state, especially compared to the nearby peers. In my time there, I dropped one class because I was worried about political grandstanding by a professor. In my senior year I took a history seminar (I minored in history because I love it) and the course title was "Modern perspectives on Che Guevara". The professor had written multiple books on the subject as well as the politics and history of the central and South americas. He didn't hide the fact he was unabashedly liberal, but he never made it a problem. The main assignment in that class was a large presentation on driving forces in the region leading to the rise of Che. I wrote about the United Fruit company. After our first presentation he called me over after the class and told me that it was obvious I was guarding what I was saying because I didn't want to offend his sensibilities. He told me not to worry about it, that my content and angle was interesting and different and that although we may disagree on the merits and demerits of the subject that he would never demean or penalize a project because he personally didn't like the subject or the attitude towards the subject. And let's be honest, United Fruit were assholes, but the purpose of my presentations was about positive changes and improvements in regional infrastructure that could be attributed to the United Fruit company, and you can certainly articulate that without an issue, so long as you acknowledge but downplay the negatives.
I ended up with a great grade in the class after writing something that, while I didn't set out to purposefully offend or be contrary with, was probably directly contradictory to what the professor believed. And he was totally and completely civil and agreeable about the whole ordeal.
I never experienced insane liberal bias in college even though it was obvious that many (not all) professors were left of center, or at least the American center. Because a decent college doesn't hire people like Kevin Allred. And if it comes to light that they did, they take corrective action before it becomes a problem, not after.
It speaks extraordinarily poorly of a college that hires those that wave their biases in tandem with their positions, and use that to further their ridiculous agendas (or shit stirring). Allred, Cicariello-maher, many others just like them are part of the cancer that makes modern academia a laughingstock to the general public outside of technical fields and hard sciences.
Aside from being a loser, Allred is also obviously mentally unstable as well. These people screech about free speech with hilarious regularity, but their incitements to violence are handwaved away and rarely punished despite the fact that they have been on the upswing in both frequency and magnitude, alongside recent violent protests and acts of vandalism.
That said, it is tough to be too harsh on a large college about an adjunct instructor. Any goober with a degree and some work experience can get an adjunct slot doing something, at least for a while.
