I'm not sure a committed Marxist would fare much better in some of the business-oriented departments than a committed capitalist would in some of the departments one would find in the humanities. I suppose it would depend on the personalities involved. Different fields often end up pushing different sets of values. This isn't necessarily problematic. The sciences are going to push skepticism in a way the humanities never would and for good reason. We might prefer to call this socialization or even dress it up as how various professions acclimate students to various fields, but it can bleed over into indoctrination if we aren't careful.
I certainly agree that the PC crap has gone way too far and has become problematic, and it isn't even limited to public universities any more.
There are pockets of liberal indoctrination taking place in many academic departments at many universities, and their are pockets of conservative indoctrination taking place in many academic departments at many universities. Very little of it is university-wide (except for the PC thing), but students leaving the gender studies department tend to have certain beliefs about the world and students leaving various departments in business tend to have certain beliefs about the world.
If I had to pick the one thing that most bothers me about Cruz - and this is no easy task - it would have to be that his particular sort of message has far too many supporters. Like you say here, American exceptionalism and Christian theocracy are dangerous. And yet, this seems to be what disturbingly large numbers of American voters want.
It is certainly well known that this is the case by people who watch a lot of Fox News, but I'm not sure I'd put much more stock in it than that. I certainly haven't been able to find anything close to a bastion of liberal thought here in Mississippi.
I wonder what the point of modern conservative college is?
I do think you are correct that the helicopter parenting style has been an important contributing factor. Not only must every kid be a winner, but it appears that any sort of hurt feelings are to be avoided at the expense of developing basic resilience.
If Phil really believes the sort of thing that has been coming out of his mouth recently, it sounds like he may be the victim of indoctrination.
People use social media for different reasons, and some are certainly after little more than an echo chamber. They may refer to them as "safe spaces," but it usually seems to be disagreement that leads to someone feeling unsafe. It is a relatively effortless way to avoid having to think critically about one's biases and the like.
Interesting question. I suspect some would argue that there is a meaningful difference between being labeled as a spammer when one has been sending spam vs. being labeled as an "MRA" or a "rape apologist" when one is nothing of the sort.
