For the same reason they complained about how video games made kids violent, or before that how the wrong kind of music would make you worship the devil.
There will always be moral authoritarians around shrieking about one thing or another. Its just a matter of playing whackamole untill they go away for the moment.
The problem with the current generation of them is that they ridiculize the cause of "equality" to a degree where it's hard to tell it apart from a massive joke.
Just look at Ayvah can you take anything serious from him/her? Besides only circlejerking around "dats sexist" i couldn't find a single worthwile argument that isn't based on personal views, subjective perception and downright trollposting. I know I'm getting baited but just look at:
This post is filled with prejudices.
It's difficult not to take the bait after starting a counter argumentation with a downright killer-statement that so wrong in itself that you don't even notice the complete lack of arguments behind it. Instead he/she jumps right to a PERSONAL narrative of PERSONAL opinnions. Why everyone else should have less of what he/she doesn't like.
However, the first thing we need to recognise is that characters exist to serve the narrative, particularly in a story-driven example like D:OS or MGSV, so it's highly jarring when a character's design is based on external factors instead of the character's narrative role.
I don't even... what is that even supposed to tell us? A character isn't just the developers tool to show you an interactive movie. It's the god damn players avatar to interact with the given narrative - that includes in the very definition a design of external factors. That includes the stylization of an aesthetic beauty standard.
Except you telling me a woman can't be a hero and fighter without avoiding her given sex and the identity connected to that. BTW, that would be pretty sexist from you.
Men get to be idealised for strength and be sexy because of their strength, not in spite of it. This a big part of the problem of catering to traditional ideals of sexiness.
And again we go; stop liking what I don't like. This time against all norms and the standard of what we find attractive. Which is infact hardcoded into our genes.
There's a reason why most people don't find fat persons attractive and why females prefer the athletic guy with muscles and prominent bone structure. Why guys doing ballette and wearing tutu's aren't exactly popular when it comes to partnersearch.
It's true that men should also have the freedom to be idealised in traditionally feminine roles (such as ballet), and perhaps there's room to style both men and women in this manner for the "finesse" roles.
Thats a privilege of our western cultural luxury and after your own arguments doesn't fit inside the narrative of a medieval world fighting over a forbidden dark magic and struggling for survival between apocalyptic events, wars and insane kings.
No thanks.
