Why is a lack of wrinkles, or a European nose or a thin waist any more arbitrary than any other measure of beauty? Saying that a hunchback, or bad skin, or crooked teeth are ugly is no less discriminatory than anything else - the people who are born with those conditions didn't choose to be. And if they are all equally arbitrary, then what is a beautiful person? I don't think it's wrong to say that being fat is an ugly feature any more than anything else is. If a fat, wrinkly woman or a bald man with a funny-looking face are both beautiful, then what does "beautiful" mean? Should AI simply output a random person who may have any features, since everyone is beautiful? Rather than trying to say that there are X features that don't impact how attractive someone is, why not just accept that some people are physically ugly, and not hold that against them?
