"Your genitals have fuck all to do with it. And they want to be equal, the fact that you can't see why this is an issue for trans people... I don't know what that says about your empathy."
Going off of this, I'm sure the following will be highly offensive, but whatever. I've already expressed this view elsewhere, and no one who knows me will be surprised by it.
Under the current setup, Lila should not be permitted to use the girls' locker room. If it is unduly harsh on her to use the boys' locker room, then letting her use the "neutral" room is a sufficient alternative. (Okay, that's maybe not ENTIRELY offensive, but stick with me.)
My reason is that transgendered insistence such as Lila's (as opposed to transgender tendencies or feelings or deep-seated mental and emotional attachments, which give rise to insistence but are not co-extensive with it) is a case of both deceit and hubris. God created humans as males and females, and for most people, He provides clear genetic (and consequent physiological) evidence of which category they fall into. (There are, of course, exceptions, but they are not at issue here.) Assuming a gender identity that differs from one's biological sex contradicts this testimony and suggests to everyone else that God's assignment of sex is irrelevant (which is a deceitful claim) and that our experience of gender identity, however arrived at, is superior to His assignment of biological sex (which is a hubristic claim). I cannot fathom why hubris and deceit would be worthy traits to be encouraged.
I must distinguish this from intensely-personal and powerfully-experienced tendencies toward transgender identity that nevertheless are not developed and manifested. These tendencies, however much they may be kept under wraps, often have very deep roots and are intertwined with the very fiber of our minds and lives. They are also not a cause for condemnation. But they are temptations toward the hubris and deceit of insisting on living out a trans life, and as with all other temptations (deeply-felt and otherwise), we're supposed to resist them and fight back against them, not give in to them and embrace them. And that may be a lifelong fight that is never completely won, and we should encourage and help and pray with and weep with those who are fighting that fight. But what we shouldn't do is just encourage them to give that fight up.
I won't deny that most of us Christians have completely missed the boat on this and done exactly what you are doing -- conflating core tendencies toward transgendered identity with insistence on actualizing that identity -- and the result is that we often summarily condemn any boys who even think they might be girls, or we think that they can only be "healed" if the very tendencies themselves are eliminated. But the solution is not to affirm those boys as girls, nor, mutatis mutandis, girls as boys.
You can accuse me of being cis-privileged all you want. I really don't care. No, I'm not afflicted -- and yes, I will use that word -- with transgender tendencies. I have plenty of other temptations that I enjoy surrendering to instead. The fact that they are by and large more culturally respectable does not make them any more genuinely acceptable, nor does it necessarily make my fight against them much easier.
My empathy lies with all those who are fighting an excruciating, daily, rending fight against themselves -- they absolutely NEED help and aid and comfort, not blithe or angry dismissal. My empathy does not lie with those like Lila who are fighting an excruciating, daily, rending fight against society so that the rest of us will affirm (and in this case, become complicit in) their surrender and their forays into hubris and deceit. You're welcome accuse me of victim-blaming, or to claim that telling someone to give up their identity and go against who they really are is itself an unacceptable thing, but you'll need take that up with Jesus (He can hear you), since one of the things that He said seems quite on point here: "If anyone wishes to come after Me, he must deny himself, and take up his cross and follow Me." And of course, any one of us who doesn't wish to come after Him has rather more serious terrors to face than those spawned from a society that isn't open-handed enough to affirm our gender identities.
