Tough question: Isn't baldness a genetic trait just like the pigment of the skin? Are you X% less attractive if you have a certain pigment of the skin?

Person's baldness was given to them at birth. They had no say in it just like the pigmentation color. What's the objective difference?

Yeah, baldness must have a use / evolutionary advantage (cooling, maybe) and isn't an illness. Like having 2 arms and 2 legs, beeing gay or having black skin color.
