You're very much missing the point. The machine obviously isn't intentionally sexualizing anyone, but it's producing a bad result, and not only is it bad, it can be perceived as sexualization (regardless of whether there's bias or not). The machine lacks understanding, producing a bad result, and the bad result is Extra Bad for some people.
Let's say I started a service and designed a machine to produce nice textile patterns for my customers based on their perceived preferences. If the machine started producing some ugly textiles with patterns that could be perceived as swastikas, the answer is not to say "well there are many cultures where the swastika is not a harmful symbol and we never trained the machine on nazi data". The answer is to look at why the machine went in that direction in the first place and change it to not make ugly patterns, and maybe teach it "there are some people who don't like swastikas, maybe avoid making those". It's a machine built to serve humans, and if it's not serving the humans in way that the humans say is good, it should be changed. There's no business loss to having a no-swastika policy, just as there's no business loss that says "don't zoom in on boobs for photos where the boobs aren't the point of the photo".
This problem has _nothing_ to do with sensitivities, it's about teaching the machine to crop images in an intelligent way. Even if you weren't offended by the result of a machine cropping an image in a sexualized way, most folks would agree that cropping the image to the text on a jersey is not the right output of that model. Being offensive to women with American sensibilities (a huge portion of Twitter's users, I might add[0]) is a side effect of the machine doing a crappy job in the first place.
