Biological differences aren't things we can easily change right now. Skin color or the shape of one's fingernails or the length of one's legs. Some biological things have real world things that go with it. Skin color, for example, could put you at greater risk of skin cancer or a greater risk of low vitamin D. One simply accepts and lives with these things and works with them.
If they are cultural or from nurture, it means that as a society, we can change things. It isn't that your tastes are an issue (mostly), but that society notices that, perhaps, men don't spend as much time with children or that women are doing things differently. In these cases, we can do things like start treating boys and girls more similarly. We can teach them similar things in school. In short, we can change how we nurture and change society (albeit slowly in some cases).
