Sounds like it's time to start organising large-scale communications to SBS that shit is entirely unacceptable. Fuck it, report the event as a terrorist threat. That motherfucker is a foreign agent trying to destabilise the country, after all!
I'm calling on anyone who can to show up and drown out his voice. This piece of shit has done more harm to American politics than just about any other currently living person who isn't an orange shitbag running for president. And, by extension, promoting fascism throughout the world.
