This has been going on for a long time. I had professors making fun of Christians when I went to college in the 1970's. It was so offensive! These professors were nothing but delusional, pot smoking idiots. Unfortunately they did inspire some students, and now those students are forming a "second generation" of university professors who are much worse!
If at all possible, send your children to private colleges that have values. Most have scholarships that make it affordable.
