Are college kids the biggest threat to free speech?

No. But I think Atrios is missing something with this:

The obsession of our pundit class with elite college generally, and specifically the idea that lefty college kids are the greatest threat to free speech ever known to man, is completely bizarre. I know that sometimes well-meaning college kids can be dumb. They are 19! They also don't have any power. Sure everybody can have a bit of power over someone or something for a moment, but structurally...college kids have no power. Even Harvard kids. The $30 billion endowment has power.

Our pundits punched hippies when they were in college (show me where the hippie hurt you, Jon) and they can't stop punching them now. It's so weird.

I suppose I'm one of the hippie punchers in this scenario. But here's the thing: College is a place one goes to learn habits of mind and habits of how to act on the ideas of what your mind generates. The students in college will, in not too long, be the folks running our offices and our states and our nation, and if they're developing censorious habits of mind that they'll take forward with them into that future, that is of concern.

That's to say nothing of that fact that colleges are supposed to be the areas of our society where inquiry and expression is most free. "Academic freedom" has covered a multitude of sins over the years - and rightfully so. When those zones of freedom become clogged by the censorious instinct, it leaves the rest of us with a reduced chance to fight for expression.

Is it important compared to President Trump threatening to investigate the press? Probably not. But it still matters, and remains worthy of comment.
