The problem, fundamentally, is that he buys into it.  His heart - her uncle's, her uncle who she's been sent to live with in a little town in California in the absence of adequate parents - anyway, his heart is in the right place, but he buys into all of it when it is just transparently, obviously bullshit.  Her mom and dad are fucking vile and he is really genuinely a good guy, is the thing, he does talk to her like she's a person, is the thing, he loves her is the thing, but the problem is that she was hoping her entire life that whoever she wound up with after she got out from under her birth parents' thumb would not also buy into it, that buying into it was part and parcel with everything else that was wrong with them.  But no, Uncle Tag is still fundamentally a guy who believes that the thing to do with kids is, you know, all the normal stuff that normal people (who don't have weird radical off-the-walls ideas about how large portions of everyone's background assumptions about the world are transparently obviously bullshit) do with kids, who do those things with kids because they are the done thing with kids, and that everything would probably work out decently okay if you stopped following elaborate chains of esoteric reasoning through to their obvious conclusions and taking seriously the moral principles on which you claim you try to live your life and trying to work out what the implications of those moral principles are, and taking that reasoning process seriously, even if the conclusions look weird, and just be more fucking normal -

That's the problem.  Fundamentally.
