Well, yeah, I suppose it depends how loud you're screaming. I was imagining someone shouting as loud as possible, which you'd definitely get stopped for in many places.
Aren't you just talking about the volume then? You could be screaming the most wholesome things about unicorns and rainbows and still be loud enough to be a public nuisance, and loud enough that authorities will have the right to ask you to pipe down.
In America, no matter how big of a community mall, management can always remove you for good reasons (using racial slurs, even at normal volume), silly reasons (they didn't like the color of your hat), or no reason at all, as long as it's not for a prohibited reason (because of your race). Whereas authorities cannot remove you from a public square for no reason or silly reasons, only for good reasons specifically identified by law (like public nuisance).

It depends if you are reported and what for. American authorities have prosecutorial discretion, so they can choose to overlook the "wholesome things shouter", but may choose to charge the "racist shouter" with a vaguely defined law like "disturbing the peace". There are enough laws like "disturbing the peace", "trespassing", and "obscenity" which are largely subjective.
