Your post is utter Left Cult fantasy. They are not hired because they are Conservatives. We all know it.
One of my staff is also a Professor of Geology at a local California State University which I will not mention, so I don't ID her, but she kept her political leanings (Conservative) a secret, because she knew she'd never get the job. She continues to keep her views secret because she says, (1) political views have no place in hard sciences, and (2) she fears repercussions if they ever learned she voted for Trump. It should never be like that.
My best friend from college is a Professor of Cognitive Science formerly at UCLA, Rutgers, and now Vanderbilt. He's was raised on a commune for a few years as his father was a Berkeley Professor of the 1970's. He's a hardcore Left leaner / Flower Child, but a great guy and still a good friend. He's quite honest about the whole thing... he says he's only met a handful of Conservative Professors in his 30 years of being a Professor.
There are very few conservative professors in the university across the world. This is not because of ideological bias in hiring, but because throughout history and until this day it is progressivism that has encouraged free-thought, liberation from dogmatism, fought against bigotry, endorsed humanism as a philosophy, and promoted scientific liberty. It's the same in the scientific establishment, medical profession, and basically any field with intellectual capital. Which doesn't mean, of course, that
a priori the left cannot be disgraceful or reactionary, or that conservatives cannot be intelligent and humanist.
The examples you mention do reflect a real problem, which is that conservatism has become unacceptably toxic in the minds of many within the university to the point of presenting threats to openness. Just a cursory look at the responses in this forum should provide a good reason why, however. It is accentuated today because of the extreme polarization. I agree it shouldn't be this way, and no faculty member or applicant should be threatened because they lean conservative, which is not to say anyone should be gleefully non-discriminated because of their views. Being pro-Hitler, Stalin, Polpot, Maduro, should not be a tolerable position, and I would be very concerned of anyone that thinks one should not discriminate against those who endorse racism and tyranny.
Sadly, the direction of the country and the current regime is bringing out the most aberrant and stupid form of conservatism we know. Just look at what some of the people in these forum say with prideful joy.
I myself got myself in quite a bit of trouble for discussing and showing points of deep agreement with branches of Neoreactionary thought, like Nick Land, and Curtis Yarvin. What the latter calls The Cathedral is a real phenomenon. I also have friends who are conservatives in the academy and share the same feelings.
But this is confusion, because what the government is doing through these measures is not de-ideologizing the university to make conservatism tolerable or to protect faculty and students that lean conservative. They are trying to brute force conservatism and suppress research or ideas that do not conform to it. Not to mention brute force closing and censoring agencies that protect and help minorities. It is only reinforcing the idea that the government is acting as an agency that promotes censorship and has racist motives.
I would be interested in hearing what your academic friends think about these 'demands'.
I should say that it is different, however, to be conservative than to be a racist, homophobe, etc. Just like there is a difference between being progressive or leftist and being a Stalinist. Under the mantle of 'tolerance' and 'diversity' one risks a kind of moral and epistemic relativism that makes overt racist, misogynist, ethnocentric, views something that ought to be represented and protected.
