That's a good point, actually for a little bit being on this forum affected how I saw myself and bald guys, reading some incredibly negative thoughts on perception of baldness on here (no guilt trip but sometimes by yourself swing) when I saw bald guys it was like a twinge in my brain going off, like I literally started being aware of them as if they are on my radar or some kind of monster or something. Like an other type of being, but really it was all in my head, and for anyone else these bald guys are just unattractive nobodies like 90% of men, hair or not.
But at the time I lumped myself further in with them, in particular the more pathetic or miserable ****s as well, and identified with that and what may be inevitable for me. I overcame this sort of sensation pretty quickly and don't really get it now, but certainly focusing on other miserable bald guys, identifying myself as one, I could easily imagine it affecting me as a stable person, and becoming more bitter and angry at the world.
Anyway back to my original point, yeah I still think baldness is generally identified as a "loser" trait, for me it won't sum a person's existence up but for example in a TV show if it flashes forward to a characters dreary future he's always in a ****ty motel, fat, and bald. Inheriting this bald trait means the likelihood of being frustrated and bitter will be higher, and that's why I think it's pretty fair for unsavoury characters in fiction to be bald guys, it's just natural really.
