"Mr. Speaker, radicalism ought not to be responded to with radicalism. I advise you bring the case to court, on charges of defamation and/or slander, alongside illegal threats of bodily and/or physical harm. I also advise you to read up on the proper law, ask former attorneys for the regions, and then provide any materials to someone you would like to serve as a lawyer.
"I will warn you that, unless you arrange an out-of-court settlement, they can appeal a ruling. Your personal morals should probably determine how you respond to defamation and slander, but the latter charges are criminal, not civil."
I understand what you're sayin, but they threatened my family... They're radicals who do not want civility... They want violence.
If it's okay with you, I advise you ask the Governor to mobilize the National Guard arrest them. From there, I would gladly argue your case in court or negotiate a settlement, whichever you want.
