Things have changed big time. Many of the Deplorables who you see as yokels actually greased your wheels by being Americans. They are tired of you. You take and take and take ang give nothing back. And you take phrases like that and reverse it. I still do not understand a inner city areas saying '''Give back to the Community"''. .Like it is owed. The cities, states and federal government have put endless resources into these areas. And the only solution is if any have gentrified.it is not nor has it ever been illegal to yell fire in a theater.I've argued this many times, especially when someone brings up the "fire in a theater" example.
You can say what you wish until someone gets hurt. Trump's rhetoric have gotten people hurt and killed.
Which is always my argument. If someone gets hurt though, then it becomes illegal.
