It's pretty clear that we need to deal with the left's mindless parroting of the word "vigilante". As with virtually everything spewing from their headholes, they have no idea what it means.
A vigilante is someone who tries to usurp the powers of law enforcement authorities for himself, but that pre-supposes there are authorities prepared to enforce the laws. In the case of Kenosha, those authorities abdicated their responsibilities. To put it another way, "vigilante" is a term describing behavior under a functioning social order. To try to apply it to a situation where there is no functioning social order is ridiculous.
As much as leftists hate it and try their best to change it, Americans are not serfs. We are not subjects. We're citizens. Those in authority do not rule by divine right, obligating us to simply accept whatever they choose to do and however they decide the world is going to be at the moment. They are servants, employees who work for us and wield authority granted to them by us. When they abandon their responsibilities and refuse to do their jobs, that authority does not remain with them. It devolves back where it came from, to the people themselves.
