Re: As for free speech
The hypothetical of "shouting fire in a crowded theater" is used almost exclusively by people who don't understand free speech theory and specifics of implementation in the US. I suspect that if most people understood that the context it was being used in was to justify imprisoning someone for anti-war and anti-draft speech they might be a bit more circumspect about it.
