Also, labels are not very helpful nowadays. It depends how you define “conservative.” William-Buckley-type conservative? Jack-Kemp-type conservative? Ted-Cruz-style conservative? Jeff-Sessions- or Orrin-Hatch-style conservative? David-Duke-type of conservative? Milo Yiannopoulos wannabe? Richard Spencer follower? All of these iterations are not the same, and I think the acceptance on campus would vary depending on the student’s definition of “conservative.”
