It’s difficult to answer the question because there’s so many variables at play. At the same university, one department can be much more politically charged than another. To take my alma mater as an example, the literature program is noticeably more “politically correct” than the English program, and the science departments are decidedly apathetic.
If you’re set on your list of colleges, the best thing to do is to wait until you have your acceptances and financial aid offers in hand and then visit as many of the viable options as possible. A lot depends on how assertive you feel comfortable being in a seminar setting and the diversity of viewpoints you want represented.
All of your colleges are very selective. Do you have a safety? UT Austin would be excellent for your interests if you’re in the top 7% of your class, and Plan II might be a good fit for you.
