I'm reading this scary article on Spiked (via onley1) about self-censorship at universities. I find this article really depressing, actually - universities at their best (or worst, depending on who you ask) when they challenge students to question their assumptions and leave the "comfort zone" they have been in their whole lives. Now it appears that schools are doing as much as they can to "protect" their students from being challenged, like forcing professors to consult a committee if they plan on teaching something controversial.
Note to universities: if you teach someone something they already know, that's not really teaching. Universities are the last place this sort of thing should be taking place. Students have the rest of their lives to practice self-censorship.
