Respectfully, IMHO it needs a tragedy to change most minds.
Whole generations have been brainwashed into believing that armed, uniformed representatives of the state will come to protect them and that the appropriate behavior is to wait for those representatives to arrive.
How much time, effort, and hot air has "our" side spent trying to convince "their" side that life does not work out well that way? Regardless if we are speaking to whole classes of people or one-on-one with an individual the ability to pierce that mindset has always proved difficult.
It's when some individual comes smack up with real life that they open their eyes, and then their mind. Sometimes they can use their experience to help others "see the light" before running smack into life themself, but all to often it just does not work out that way.
stay safe.
