@Junkyard, maybe you live in an alternate universe where the roads aren’t seemingly chock full of people who are willing to escalate to violence at the drop of a hat, same with those who like behaving like pigs in public.
More often than not, they will escalate to violence for very little, and even more so if they perceive weakness or vulnerability.
If you want to go around thinking we live in this nice polite world where you confront these people and walk away unscathed, that’s your shout, just don’t expect the rest of us to be that naive.
Nobody deserves to be assaulted, but sometimes that is going to be the consequence of doing the right thing. Or doing nothing, some people need no provocation to attack, they will find it themselves.
