+I can't say this causes any problems, because that would depend on how you choose to draw the category boundaries around what constitutes a "problem." But objectively, injecting a substantial fraction of otherwise-ordinary-but-for-their-gender-dysphoria natal males into spaces, roles, and categories that developed around the distribution of psychologies of natal females _is_ going to have _some_ sort of nontrivial consequences (whether you judge those consequences to be good or bad).

+A (cis) female friend of the blog, a member of a very ["Blue Tribe"](http://slatestarcodex.com/2014/09/30/i-can-tolerate-anything-except-the-outgroup/) city's rationalist community (that is, basically the same group of people generating the _Slate Star Codex_ survey results just mentioned) reports on recent changes in local social norms—

And it's hard, because it's weird and uncomfortable once three or four participants of twelve are trans women. I think the reality that's happening is women are having those spaces less—instead doing private things "for friends," with specific invite lists that are implicitly understood not to include men or trans women. This sucks because then we can't include women who aren't _already_ in our social circle, and we all know it but no one wants to say it.

+But this is a _terrible_ outcome with respect to _everyone's_ values. One can't even say, "Well, the cost to those bigoted cis women of not being able to have trans-exclusionary spaces is more than outweighed by trans women's identities being respected," because the non-passing trans women's identities aren't being respected _anyway_; it's just that (cis) women are collectively too _nice_ to [make it common knowledge](http://slatestarcodex.com/2015/10/15/it-was-you-who-made-my-blue-eyes-blue/).

+People should get what they want. We should have social norms that help people get what they want. Unfortunately, helping people get the things that they want is a hard problem, because people are complicated and the world is complicated. That's why, when renegotiating social norms to apply to a historically unprecedented situation,

+As a transhumanist as and as an individualist, I want to protect people's freedom to modify their body and social presentation, which _implies_ the right to transition. For the same reasons, I want to protect people's freedom of association, which _implies_ the right to transition.
