OH MY GOD YEAH. its so wild to me that luka is considered one of the older vocal synths just because she isn't a highschooler. the more extreme and inexcusable examples come from feminine vocals (in every language, but english vocals seem to be better about this), but even the male engloids are ridiculously young (i am a strong middle aged sweet ann + big al believer, its ridiculous they were retrospectively made to be in their 20's)Like, maybe we should be thinking about why so many vocal synth characters are portrayed so young by their creators?
also i agree that its extremely horrifying that a common consensus among straight men is that attractiveness is amplified when the girl is younger and women need to fit a very rigid box to be seen as attractive. its especially scary that women need to be seen as attractive in the first place to be seen as human. this applies to fictional characters, too; its so common to see conservative men throw a fit everytime a big video game series's protagonist is a woman that isn't an idealized version of their type (or even just any black or not very skinny woman).
The main thing i think of in terms of is early Meiko portrayals, where she's seen as an unsympathetic old hag despite often being under 30. You have to respect everyone and be nice to them even if you aren't attracted to them. I wish others can respect women no matter what.
