Children need to be taught young that most adults are liars, schemers, adulterers, grifters, gold-diggers, whores, cucks, simps, perverts, etc., including a majority of their own parents, aunts, uncles, and grandparents.
We're not going to change the behavior of adults. The least we can do is warn children about who they walk amongst. We tell them not to talk to strangers due to potential danger. We also need to teach them to "check their six".

I thought it was the milkman ;-)
