What a nightmare.
It’s a sovereign citizen.
Someone down voted you, but the part about spouting irrational Magna Carta nonsense checks out.
I think the downvote from someone not bothered enough to say “well duh” but also bothered enough to signal their annoyance…
The article references sovereign citizen specifically.
“He shouted, ‘Why are you in my house, this is my house - it’s been decreed this is my house”.
This is what you get when there’s a failure to address the issue of online conspiratorial thinking getting amplified by social media networks unchecked against a backdrop of mental health disorders that aren’t properly treated. I don’t know how you reduce the online aspect of it without curtailing freedom of speech, but it’s a real problem and it isn’t going away.
