Femininity and masculinity are the names for the expressions traditionally associated with biological sex. But these expressions -- from liking pink to hating to ask directions -- are cultural, and do not always map precisely with biology. The call for more choices and fewer stereotypes is not about undervaluing girls or hating pink. I don't hate pink. The only color I truly hate is that yellowish green that looks like snot. I believe that people should be treated with love and respect, regardless of sex, gender expression, or sexuality. Finally, I believe that sex, gender expression, and sexuality are not binaries, much less opposites.
I *do* hate essentialism ("girls naturally like pink"). I also think that when we stereotype something as "masculine" or "feminine", we ignore real and important variations in human nature and expression.
No one should hate pink; it should just be a color. Save the hate for snot green.
