Its too easy to pull a gun and threaten with lethal force, thats how situations escalate quickly and you have no point of return.
If you're trolling, fuck you.
If you're ignorant, none of the things you listed are any more functional than a functioning body and a small small folding blade. You avoid until your life or safety is threatened, then you dispose of the threat. That's the American way. Our country was great for centuries of living by that philosophy. I don't consider it coincidence that our culture has turned to shit in the same timeframe that the philosophy has swayed to that of appeasement.
Pulling a gun and threatening with lethal force is neither quick nor easy. Being threatened with lethal force on the other hand, is exceptionally quick.
