Daniel Davis:

For years, a major aim of the sexual revolution has been to deconstruct gender differences as being “social constructs,” mere cultural projections of what maleness and femaleness are and mean. This critique evacuated gender of any physical meaning and reduced it to an existential feeling—a feeling of being male or female, regardless of one’s sexual biology.

The effect of this critique has been to relativize gender, and thus to abolish it as a meaningful category. Because you can no longer tie “femaleness” to a normative set of traits or acts (for example, wearing dresses or marrying men), the category itself cannot help but lose its meaning. To call any particular act a “male” or “female” act would be to revert back to antiquated, repressive, patriarchal norms—norms that only serve to foster social inequality.

This is the ideology that governs liberal sexual philosophy, and it collides head-on with major aspects of the transgender movement. Transgenderism is unavoidably based on a kind of gender essentialism. It recognizes gender identities as being associated with certain socially accepted norms. What does it mean, for example, that Jenner’s “gender” is female? It means that he gets a sex change. It means that he poses in traditionally female attire for the cover of Vanity Fair. It means that he reaffirms traditional gender norms, even as he attempts to flee from them.

In fact, he cannot help but reaffirm them, for they are the only tangible way of expressing gender. Inner feelings must inevitably take on flesh, and gender—understood as a mere feeling—must inevitably express itself in material form.

This is a problem for the broader liberal sexual movement. It wants to celebrate transgenderism, but it cannot do so without referring to—and thus, at least tacitly affirming—gender norms. To celebrate Jenner’s femininity is actually to commit a liberal heresy: to revert back to a form of gender essentialism.

There’s a flip side to this coin. As we noted, liberal sexual philosophy strips the term “gender” of all normative meaning. It reduces gender to a cultural phenomenon. In doing this, it robs transgenderism of its key claims to gender authenticity, and therefore of its right to moral affirmation. Consider it this way: If gender has no real connection to biology and certain social traits, then someone’s claim to a gender identity is virtually meaningless. And if it is meaningless, how can we be morally obliged to recognize it—let alone even understand it?
