Yes and saying that sex and gender are different paves the way for the whole self ID stance of the trans movement. It used to be called being transsexual because it was about the desire to change one’s sex, one’s body. You couldn’t be trans unless you had changed your sex. With the creation of gender, it no longer has to be about the body, because gender is seen as separate from the body. The entire idea of gender is completely stupid, there’s no such thing, it’s a made up imaginary thing in the sky, just like god or the devil is a made up imaginary thing in the sky. All we are is our bodies. Everything else that people call “gender” is just our individual personality traits.
