When does freedom of speech become treason?

[Speaker to Animals]

Here's an interesting case:

Scales v. United States, 367 U.S. 203 (1961)
https://en.wikipedia.org/wiki/Scales_v._United_States

Dennis v. US:

In the plurality opinion, the Court held that there was a distinction between the mere teaching of communist philosophies and active advocacy of those ideas. Such advocacy created a "clear and present danger" that threatened the government. Given the gravity of the consequences, the Court held that success or probability of success was not necessary to justify restrictions on the freedom of speech.

Did not expect seeing that. So, does this mean an American Socialist (or any other who wanted to simply advocate any competing different system of government) could get arrested simply for talking about it in public? If so, why isn't every single Socialist and Communist (and others) behind bars?
My OP question asks if people should go to prison for that. So my interest isn't only in the facts of what the courts have said, but if you and others here approve/disapprove, about what things should be like. I do very much appreciate gaining more insight on the issue as it is, however.

I need to get back into that. My wrists have been giving me fits lately, though, so I'm trying to stay off my laptop at night.

If a government is so fragile as to be threatened by the mere mention of an alternative, then it doesn’t have long to live anyway.

And by treason, I mean the sort you should go to prison and/or an execution for.

For example, in an American context, should Socialists and Marxists go to prison for treason for either speaking about to other people, advocate for, or trying to organize political parties meant to advance Socialist ideals?

Or...

Should the charge of treason be reserved exclusively for those who attempt or plan to change the political system by force?

Your first example is exactly what the 1A protects from
