There's still a huge blind-spot in the general public's conception of gender. Transsexuality challenges patriarchy and the notion of male dominance and superiority much more than it does gender as such, and because of that the essential idea of an absolute gender binary remains. From a personal point of view, I think many people that transition multiple times are actually probably androgyne or neutrois or other forms of transgender, but in the same way that transsexual people experience the pressure to conform to their birth sex, transgender people experience the pressure to conform to one or the other and stick with it. The idea that gender and sexuality is fluid in some people, and that that is as it should be, is still very alien to most people. Even my mom, who is one of the most open-minded and accepting people I know, has trouble getting her mind around somebody who identifies with both male and female equally, or with neither one at all, or varyingly with either one. It's too bad that so many transsexual people are quick to attack those identities, or judge detransitions so harshly, when really, those people are on their own path of self-truth, and deserve the same support and acceptance as anybody.
