Wow. These are the free-speech rankings for colleges in the US:
https://rankings.thefire.org/rank
Of the top 6 that are rated "Good," L=Liberal to C=Conservative ratios are telling:
1. University of Chicago, L:C = 4 : 1
2. Kansas State University, L:C = 1 : 1.3
3. Purdue (main campus), L:C = 1.1 : 1
4. Mississippi State Univ, L:C = 1 : 1.9
5. Oklahoma State Univ, L:C = 1 : 1.2
6. Claremont McKenna, L:C = 5.2 : 1
The bottom 6 (Poor, Very poor or abysmal):
198. Yale, L:C = 5.2 : 1
199. Skidmore, L:C = 11.8 : 1
200. Georgetown, L:C = 3.3 : 1
201. Rensselaer Poly, L:C = 2.3 : 1
202. U. of Pennsylvania, L:C = 5.9 : 1

Looks like there's been a flip in the definitions of liberal and conservative, at least wrt free-speech
