There are lots of “movements” that are kinda nutty. But outside of the religious or occult, it’s hard to get more downright delusional than “sovereign citizens,” especially the ones who base their bad behavior on patently ridiculous re-writings of history.

Man arrested after extremist group takes over Newark woman’s home, police say

Short form: a member of a “Moorish” sovcit group broke into a woman’s home in New Jersey, changed the locks and claimed that it was *his* because, as a “Moor,” he has ancestral rights to all the lands in the US and doesn’t have to obey US laws. He apparently thought that that would be the end of it, that the rest of society would accept his actions and let him keep the house. This is not just wrong, it’s loopy and stupid; anyone with a  functional brain would have told him:

The local police responded correctly: a bunch of guys with guns showed up to convince him of the errors of his ways. Fortunately they got him out without shooting up the joint.

I can easily see a lot of other homeowners being a whole lot less patient with this nonsense. It’s your home; I can’t imagine that there are legal issues with you breaking down your own door. If you break down your own door and find someone unwanted in your home, Castle Doctrine would now be in play, I would expect. If said homeowner is a popular person, gifted with many friends and family given to muscles and enthusiasm, the home invader may find himself in a spot of bother.
