unless -- based on personal experience -- if it's treated as suspicious by the local police/neighbors, even if its a skinny, geeky-looking, white male who goes out walking alone late at night.
if I had a nickel for every time I've been harassed by police or local do-gooders, I'd have a lot of those nickels. and I'm not even of the demographic that PC-ness says should be oppressed. (ostensibly: black+male, or male+gay, or non-white, or female, or mean-faced, or weapon-carrying, etc. in reality: straight white male, innocent, no weapons, not in a gang, no drugs, etc.) "why are you walking alone at this time? why are you looking at things? implied: are you a terrorist? a pedophile? explain immediately!"
We do not (always) live in an intellectual-friendly culture. At least not in the USA, 2017. We (might, often) live in a small-minded, hyper-stereotyped, very ignorant local culture. Obviously it depends on precisely where you live. SF on Friday at 8pm? very different than Kansas, small town, Wednesday, etc.
not even joking. (And I submit this knowing it's not a HN-hivemind/PC-aligned viewpoint, and thus will be downvoted. I do not care anymore.)
