That analogy is rather good here because it has a dual interpretation - in terms of the actual history that could be dredged up by wiki editors [0] yelling fire in a crowded theatre has led to ~81 stupid deaths globally and failing to yell fire at an appropriate time has led to at least 278 really stupid deaths in the US. In practice there, there is evidence that yelling fire is not encouraged enough.

There are real threats that are mitigated by an open and tolerant approach to speech. Cracking down on people will lead to a culture that is really bad. Which should be intolerable since the crackdown is only trying to defend against things that are mildly annoying.
