Many a man that says he cares about privacy also doesn't really care, to be honest.
One thing that has always irked me is the carelessness by which a man may give out, and is expected to give out, his full name.
Almost everyone has accepted that this is a bad idea on the internet, but in corporal social interaction full names are given out as if they be blowjobs, and so much information can be uncovered from a man's name.
It needs some serious revisiting and consideration how this works and I think in today's modern æra we probably need to do away with a single unified name for all purposes and allow citizens to operate under pseudonyms depending on the setting, at a minimum to keep one's professional and social life more separate.
Another issue is visible faces in public. My jurisidiction on the eve of the corona pandemic actually passed a lot to ban full-face covering, worded neutrally, but everyone knew it was about certain Islāmic garments. Supposedly it was necessary that every citizen's face be publicly recognizable, yet now we all cover it with masks to no problem whatsoever.
Even without a pandemic, a man should have the right to obscure his face in public and be unrecognizable for whatever reason he might desire.
