The thing is, if you are a trans person, you understand the difference between sex and gender, and being a trans person means acknowledging that there is a dissonance between your own. Having said that, if you are a trans person that doesn't have gender identity disorder, you embrace the fact that you are a man who is a female or vice versa. Which is absolutely 100 okay. What's not okay is covering up that dissonance by avoiding it completely. That's what gender identity disorder is.
