Defending human rights is not being politically correct

Overtime starts with Maher asking Harris-Perry about college political correctness, which Maher thinks is rampant. Later though (4:40) he talks about liberal values and human rights that are better than others, like freedom of speech, separation of church of state, respect for minorities and women. It's exactly those values though that the college kids are standing up for, not tolerating bigotry and racism and xenophobia. Those things aren't politically correct, they're right. And college kids are right to defend them. Calling them PC is a regressive Republican meme.
