A hopeless tactic. No, the solution is to build new universities that are fully committed to western civilization and objective truth, that rigorously discriminate against wool gathering and bathos, fully willing to flunk and fire anyone spouting drivel, treason, or immorality.
Then staff them in the first generation with think tank conservatives and the students of the remaining conservative cadre in the old universities. And then encourage a significant portion of those who graduate from them, to teach, themselves.
It will take decades and billions, but it is well worth it. Nobody will care about the Stanford faculty when everyone knows they are putting out crap and there is better stuff available. They've wrecked valuable institutions - build new ones. And don't let them back in to wreck those, too.
Save some time and money; "commandeer" some existing ones.
