I just mean that culturally it's the classic example that people would always bring up to illustrate the limits of free speech. The legal standard is a different question of course. But that's part of the issue here. Free speech isn't just a narrow legal question. It's a cultural value, and it's under assault in a way we've never seen in our lifetimes. The fact that "yelling fire in a crowded theater" was never actually the legal standard (which is interesting by the way!) supports this point.
