Tom Blumer observes that our leftist universities and their ilk possess and abuse their power to destroy careers and control people's lives. The communists, he says, constructed checkpoints, whereas our leftist leaders use "chokepoints":
Those who occupy positions in university systems, government bureaucracies, as well as certain union and professional organizations, often with the active assistance of the courts, serve as the system’s “Chokepoint Charlies.” You can’t get through or move on unless you jump through their hoops, comply with their demands, or behave according to their established norms.
Here is Blumer's take on campus chokepoints:
In university systems, the most obvious chokepoint is tenure. If you achieve it, you have a position for life; if you don’t, your career is essentially over. Not surprisingly, leftist-dominated universities have used denial of tenure as a principal means of culling promising conservative professors, or even usually reliable liberals who utter occasional center-right thoughts, from their faculties’ ranks. Other university chokepoints are in the classroom. For the most part, it’s still true that if you’re bright enough, apply yourself, keep your head down, and avoid making too many waves, you’ll get through. But if you happen to incur the wrath of an intolerant radical prof by expressing a dissenting view, no matter how well-supported, you may find yourself with a failing grade, a lengthy redress or appeals process with less than assured results, and perhaps the inability, at least at that university, to go on to the next step in your desired major. Perhaps the most dangerous chokepoint at universities is in research. If your line of inquiry leads to conclusions that are contrary to established beliefs — say, just for the heck of it, if you find evidence that the earth really hasn’t been warming, or even if it is warming that it’s not significantly influenced by human activity — there’s more than a slight chance that your “peer reviewers” won’t be impressed and that your next funding request may not be granted. Just like that, you’re on the outside looking in.
