I believe this is the same issue with the other comment, taking what I wrote as a specific solution to a specific problem.

This issue of getting the police called is emblematic of a problem that dark-skinned people have, where they're considered to be inappropriate for natural areas.

What I was getting at is that there are specific rural areas, with unhinged residents and poor policing, where no outsider should go. If I choose to go, I should expect to provide my own personal protection. Those locations would be vastly multiplied if I had dark skin, to the point that it might become more expedient to just always carry.

I'm certainly not saying it would be appropriate for anyone to arm themselves while hiking in the Alps, or when dealing with police or benign racism.
