@jk I'd say, good riddance to them
I've lived in all kinds of neighborhoods from super polite people saying "Good Morning" and such to "what are you looking at, punk?!" You adapt to your surroundings while remaining respectful toward others. Whatever else, not being the instigator of conflict and avoiding creating bad feelings for anyone
If these people can't observe a modicum of restraint or if they so badly need to be an ass for no reason, they don't need to be here
