“The basis of most arguments against trans people is that we are not who we say we are, that we are always and only the gender that we were assigned at birth. And so much of that is about having a sense of certainty around gender, that when you were born with a certain set of genitalia, then that must dictate your entire life, and the reality is that that’s not true. A lot of people are not comfortable with that, because then that means they have to begin to question who they are.”- Laverne Cox
