Unless they're cloistered in math & physics departments, but even there they're not completely free from liberalism.
I love how the FSSP seminary website puts it in its FAQs page:
The FSSP has a way with understatements, no?
If college or university is needed, take classes on line. If you must do it in person, do so as an adult. Establish yourself off-campus, living quarters, chapel, job, social contacts, the works. THEN go to class. Work your way through as much as possible. Do not ruin your life by graduating with a worthless piece of paper and the equivalent of a thirty year mortgage on a house. Don't ruin your parents' lives by bankrupting them, or worse, bankrupting them and moving back in with them.
