Right idea, wrong conclusion.
You're right - evil doesn't justify evil.
Meaning you don't commit arson just because all the cool kids do it.

But here's what you got wrong:
Tolerating evil is what actually perpetuates it.
Punishing evil isn't evil.
Punishment is a deterrent.
(The very fact that people pay taxes shows it)

Zechariah 3:2 "The LORD rebuke you, Satan! [...]"

Yeah, you get it. It begs for friendly intimacy between the writer and the reader in an uncanny way. Comes off as being disgenuine. Like someone trying to bond with you after viewing you for a week through a one-way looking glass. You know the person knows something you don't, and is not giving you the whole picture (for selfish reasons no doubt). "Folks" is a very safe word to use when you're trying to be extremely careful and deceitful in an attempt to grant the readers a false sense of familiarity and trust. I ***ing hate those people

The word "folks" is a credibility killer

She can *** me up

What rapists? Oh, you mean our student atholeets?
