It's not just them, you've got ebikes going 30mph, kids/teens congregating on bikes in balaclavas. Come look for yourself and see if you don't feel intimidated.

Oh! I live somewhere like that. I just don't be intimidated by things unless I have a reason to be intimidated. Although scary looking people congregate sometimes, they've never actually harmed me so I don't avoid the whole area. And the few times I've ever interacted with a scary looking person, they were chill.

Tendency to fear has to be one of those personality axes. Studies found that political conservatives have larger amygdala (the part of their brain that governs things like fear) so maybe this is something similar.

AH! THE YOUTH!
