Universities should prepare people for life. By encouraging free exchange of ideas, including uncomfortable ones, we force young adults to strengthen their arguments through dialogue and debate. Safe spaces create ideological echo chambers where people can't learn.

It's also disturbing to hear "dissenting" opinion equated with violence - that just encourages physical violence in response. It's autocratic group think and it really needs to stop. The world outside the academy isn't so forgiving of garbage tribal behavior like that.
