Feels a tad controversial to say so, as many nowadays consider gender roles oppressive, and condemn 'gender essentialism' in favor of some sort of neuter ideal. We humans do have a sordid record of forcing each other into restricted roles based upon gender, skin color and so on; I suppose our skittishness on the matter is understandable.
No one should be pressured to adhere to any rules of gender. We ought to all be free to express ourselves, gender-wise and otherwise, as we like. This seems an obvious platitude. And yet, we might remind ourselves how widely it applies, scolding not just icky misogynists with retro notions of femininity, but also Women's Studies majors who would denounce my tight jeans. Both, after all, implicitly impose their own gender ideas on others. My ass is mine to objectify as I please.
