An armed citizen carrying a concealed handgun is making a withdraw from an ATM.
An attacker attempts to rob the citizen; the armed citizen kills his attacker.
That’s an example of appropriate, lawful self-defense.
A rightwing racist travels 20 miles to another state where he has no business being, intentionally places himself in a potentially dangerous situation, with the hope of killing an American of color.
He lies about ‘protecting’ a business whose building is empty, whose owners he doesn’t know, he lies about being ‘EMS,’ and he’s openly carrying a semi-automatic carbine in anticipation of killing an American of color.
This is not an example of appropriate, lawful self-defense – it’s an example of reckless, irresponsible, criminal vigilantism.
