Monstro is even more wrong than everyone else. A society that does away with gender entirely - one that does not decide that because you are male (a physical attribute) you must be attracted to women, like sports and hate pink - makes sense. Increasing the number of boxes to put people in from two to three does not.
Transsexuals are like the religious right: idiots who hold a counterfactual worldview who think it’s hate speech to not treat their worldview as true.
