It's certainly not a strawman when it's an oft repeated argument going back to Oliver Wendell Holmes' dictum in Schenck v. United States (and even further, as Holmes didn't invent this argument). The argument doesn't change if it's "There's a fire! Run, everyone!" -- and saying "that isn't speech, it's an emotional trigger" would be an intellectually dishonest evasion--lots of actual true blue speech triggers emotions.

P.S. I won't engage further with people clearly not arguing in good faith.

There it is. Actual true blue speech triggers emotions.

Speech communicates ideas. It is mostly opinions. If you state something as fact, when it isn't, it is libel. As such, saying "there is a fire" in the theater is not speech, it is an exclamation.

If you aren't for free speech, then yes, yawning is speech.
