Citizens United removed the limits on the international money as well as the domestic money.
Why is the countey tearing itself apart? Because the foreign money has interest in weakening, stealing, amd profiteering from the USA.
Conversely, the domestic money wants to keep the domestic part from falling completely apart; at least until the real estate, votes, and grant money for the revitalization project are all lined up.
People ready and willing to spread violent, harmful hate can be dealt with via the laws they violate. Assult, battey, stalking, theft, etc.
The subtle side is, as always, if your speech cannot persuade the (large) majority that the opposition speech is wrong, then to dismiss the opposition is to become the oppressing minority.
I so wanted this to read:
You sick pervert.
