There’s roughly 1.5 million post-secondary instructors in the United States, roughly half full-time.

Estimates of conservative faculty range between 7-15%. (FIRE, where the 15% figure comes from, probably overestimates due to their conservative bias.)

So approximately 50,000 to 110,000 conservative faculty. You’re off by a couple orders of magnitude.

There’s over 500 faculty working at Liberty University alone, never mind the other, larger Evangelical Christian schools.
