I also can't make sense of the article. The 1A clearly doesn't protect you from prosecution if you deliberately cause a disturbance by shouting "fire" in a crowded theatre. It's an uncontroversial example illustrating that the 1A has limits. The fact that this uncontroversial example was used in support of some controversial arguments ~100 years ago is neither here nor there.

> People use "fire in a crowded theater" as a valid exception for the taking away your 1A rights. "Fire in a crowded theater" was used to as an argument to support government censorship of wartime dissent. Think of what that means.

I'm thinking, but all I can see is an apparently sincere effort to make the argument that Hitler Ate Sugar ( https://tvtropes.org/pmwiki/pmwiki.php/Main/HitlerAteSugar ).

So tell me: what does that mean?
