Daniel is right: free speech should be protected. Campuses are becoming increasingly inhospitable to free speech. Opposing viewpoints (anything that doesn’t follow a hard-Left line) are stigmatized and demonized (not refuted). Speakers generally present only one point of view. But treason and sedition? Not protected speech. And it is quite likely that Daniel would say that AFDI, an entirely peaceful group that advocates nothing but the enforcement of existing laws, should be banned from campuses. But not the Islamic State.
