When we respond to the transgender issue by pointing out that biology makes it clear that there are only two sexes, we are attacking a straw man.

Gender ideologues do not typically deny that sex is binary. What they deny is that our identity is limited to or determined by. In addition to our sex, we also have a gender and gender-identity. Gender is a social construct related to the different behavior and roles men and women play in society. Gender-identity is one’s perception and deeply felt experience of their gender. Most people’s gender and gender-identity matches their biological sex, but some people experience a mismatch. They may have a male gender-identity but a female body. In such cases, they should be considered a male because gender, not sex, gives us our identity. Some transgender people may desire to alter their body to match their gender, but others may be comfortable with their body. That’s why it’s perfectly legitimate to speak of men with uteruses and women with penises.

There can be a lot of different gender identities because gender is not tied to biology. As a social construct, gender is malleable. There can be as many genders as there are people because each person could see their role in society differently.

This is why you can’t undermine gender ideology by pointing to biology. Biology is largely irrelevant to gender ideology. The way to defeat gender ideology is by questioning its basic presuppositions:

  • Why think gender is a real (ontological) category?
  • It’s said that “feeling like a woman” is what makes a man a woman, but how could any man know what it feels like to be a woman? He would have to know how other women feel and then compare that to the way he feels. That’s impossible. He can only know how he feels, and he has no way of knowing if the way he feels is the same as the way women feel.
  • What is a more reliable indicator of reality: feelings or biology?
  • Why think that gender defines our identity rather than biology, particularly when biology is objective and gender is subjective? Our biology can’t be mistaken whereas our self-perceptions are often mistaken.
  • Etc.
