I wonder if it could be because masculinity is being challenged on campus in the current era. Why would a male who has issues with women want to go to a place where he will be challenged to change his views in sensitivty and toxic masculinity courses? Conversely, why would a male who does not have issues with women go to a place where he will be labeled as having toxic masculinity? It's not like these issues haven't been all over the press for years.
