You’re arguing about highly specific cases while the vast majority of institutions get on with the job of educating large numbers of students and doing what research they can.
The highly specific cases are glaring examples that the unbiased meritocracy they pretend to be is, possibly, not so.
And the "large numbers of students" covers up the possible cronyism and/or corruption of the institution.
I provide an example of a totally unqualified individual being allowed into a prestigious institution solely on the basis of his marriage family. Your response is that they mostly do a good job for most people?
I've suggested that the research they do is not obviously beneficial to anyone except perhaps the person doing the research, possibly simply to advance their own careers (in or out of academia). Others have suggested the same.
It sounds like you can't defend your position and resort to (I think?) name-calling, although I have no idea what a "culture war poster" is - I used to have a poster of Farrah Faucet in a red bathing suit, is that the same thing?
And I have no hobby horses, just a high horse, and you better hold your horses or else you'll be just be whipping a dead horse.
Your unwillingness to defend and advance your position is duly noted. Have a nice day.
