It’s not a federal matter.
It’s not terrorism.
Call the cops, get a restraining order. Be prepared to defend yourself if you have to. That’s what victims of domestic violence and similar threats do.
As far as the subject of the thread goes, I take it you approve of the DOJ being involved, and having the FBI use its resources to go after parents targeted by local school boards - like the man in Loudoun, VA.
Unfortunately, it is now nationwide, and therefore federal in scope. I remember when socialists and anarchists did this years ago, and the feds were empowered to go after them. I could care less about left or right when it comes to extremism, violence, threats of violence and other things outside the scope of democratic law and the Constitution.
I think any major uptick of threats or violence nationwide needs to go on a radar screen and followed, no matter ANTIFA, Blackbloc, Revolutionary Socialist Brigades, Proud Boys, Three Percenter, Oathkeepers, no difference. Like Crips vs. Bloods in my book.
