I see there’s a lot of court cases listed in that Wikipedia entry so it seems like it'll have to be decided by a judge on what is considered free speech or not, because language by nature is vague and can interpreted in many different ways.
So there is no such thing completely “free” speech if there are constraints.
Have you read any of the cases? They get pretty detailed about what is and isn’t allowed. This is not the first time we’ve been having this debate - far front it. Though, some seem unaware that there’s a substantial body of court history on the subject, both American and otherwise.
