We shouldn't be using taxpayer money to pay for people to be indoctrinated by marxists for useless liberal arts degrees.
Putting aside the Marxist tripe, I would argue that that cuts both ways, at least in K12. Taxpayers shouldn't be paying for kids to be sent to religious schools via voucher programs. Nor should we be so lax with charter school funding, either.
The people calling for this are a handful of backbenchers in state legislatures. This is nothing short of whataboutism trying to pretend as if "both sides" are equally hostile to free speech-- but on campus, it's abundantly clear who the people hostile to free speech (or at least desirous of placing onerous burdens on its exercise) are.
It's not all about trying to force universities to hire conservative professors. It's about conservatives trying to starve schools they don't like of funding. It's been happening in a lot of places.
