Better yet, IGNORE them. Remember that these organizations only exist because they have viewers so WALK AWAY. Don't give them your attention. Don't give them your money. If you know of a company who advertises with them, don't buy their product and let them know WHY you're not buying their product. Vote with your dollars. They will take that a lot more seriously than they will take threats of violence.
This is exactly the way that Dems have taken over so many "working level" positions in the country, and there is absolutely no reason that we should not do exactly the same thing. Get involved in politics at the local level. Get out the vote. Ensure that elections are LEGAL and FAIR. Nothing wrong with any of that. We tend to grumble a lot because things are not being done the right way in this country, but how many of us are willing to get off our butts, take one of these unfilled slots, and get busy seeing that our candidates are elected? And then held to the line? Good idea, and its time may have come.
And the Dems found and cultivated up-and-coming young people via their community action organizations and worked them right into the existing system. Most of them just think that's how it's done. They're probably surprised when they're arrested because they've been doing it that way for years and nobody has done anything about it up until now. Kip Simpson has been documenting arrests and convictions on his YouTube channel for years.
