I’m not worried about street people slurping my traffic, and I’m not worried about hotel guests/staff snatching my laptop. It’s not a monoculture.
And if you were at all familiar with the neighborhood I’m currently in, you wouldn’t be calling it “paranoid class and race based fear,” you’d call it a perfectly reasonable decision not to blithely flaunt valuable electronics in front of people literally shooting meth in the alley outside my front door.
