Ive seen this not work in some cases. When i was in the service in Iowa for instance, police did not respond at all to situations like this unless they witnessed it themselves. Even then getting a consequence for the offender was hit or miss (usually released with a warning).
I had 3 football players put me in the hospital because my friend flipped them off when they made unwelcome advances to our gfs, when i first got to Iowa after boot camp. As a result, I had a concussion, lost a tooth, broken nose, bruised ribs, and several broken fingers, and nothing came of it. My ‘friend’ ran as soon as he saw them jump out of the van, and I turned around to see why he ran and boom I was getting wailed on. After that, i started learning to defend myself with the resources the service offered
The west coast is a little bit better with enforcement. Still…I hear active protestor friends of mine tell stories about being spit on by anti maskers though, and nothing comes of it for consequences either (the specific example that was running through my mind).
In my experience, there is the letter or ideal of the law, and there is the practical execution of it, which often allows offenders to get away with it.
Spitting is just a hypothetical example, I have more extreme real life examples that I could either walk away from, or hold the line against ‘might makes right’.
I dont feel bad one whit, for holding the line, when bad plays out in front of me (without resorting to anger or further aggression, and limiting it to it as a example of what is being thrown around)
EDIT: Standing up for whats right doesnt mean you are mightier, just means you wont let wrong/evil go unanswered. It may cost you broken bones, or your life, but often bullies back down when called out as well. Its just not being ok with wrong running amok and standing up for whats right, and NOT waiting for someone else to fix the wrong. Though Ill admit im 6 3 bigger guy these days, so i may have some inherent privilege because of that factor, but it was a also huge deficit when i was young and sought to avoid conflict at any cost.
