Re: @Kiwi ... "You can [..] draw a conclusion that bad actors are going to [..] do bad things."
So how do you teach people who don't want to learn and if push came to shove would rather fight you than surrender?
You use your brain.
Sometimes, that requires waiting for "divine inspiration" (and yes, I do mean that in the literal sense - it's probably the rightmost black arrow on the bottom left of the post you want to hit :) )..
And sometimes you just let herd mentality do its job. Can't fix stupid? Go do what you can elsewhere. Peer pressure and leading by example are very effective tools.
