I didn't read the entire article.
But here's what I'd suggest:
1. Cut off state funding to colleges and universities that punish conservatives and free speech.
2. Not only that, cut off their accreditation, as well.
3. Eliminate tenure for professors. Not sure if this can be mandated at the state government level, but if possible, do so.
4. Pass laws that guarantee the right of students to express opinions without reprisals from faculty or college administrators. If the schools won't comply, have penalties, including fines and prison sentences, for those who obstruct such freedoms.
