Nobody has the "freedom" to be free from upsetting messages in public spaces.

Why not?

Why should anyone be FORCED to listen to someone or read their message?

Plenty of "public spaces" have a designated purpose and rules restricting their use. (E.g. The White House, your local high school, &c.) Roads and sidewalks are for getting from one place to another.

Roads and sidewalks are for getting from one place to another.

And as long as speakers don't prevent anyone from getting from one place to another, they are within their First Amendment rights to speak there.
