Let’s look at this from another angle, shall we?
Was this guy or a member of his family victimized by blacks and nothing was done about it?
Were any of his kids assaulted by blacks in school and nothing was done about it?
Was his wife, sister or daughter raped by a black man and nothing was done about it or worse, they were told that they deserved it because, you know, white privilege?
Any of these incidents could trigger a reaction of extreme anger and hatred towards the perpetrator(s).
It’s what our rulers want, anarcho-tyranny is purposeful.
They want people to snap.
They can institute more draconian tactics when things get bad enough.
They want people to ask “for their chains”.
Good salient points
