Basically, what you said.

(I mean, we could argue the details of what relatioships the gvt should recognize and how that would work and I kinda think the gvt should only recognize parent/guardian-child relationships but I just don't give a fuck really so long as it's a) properly inclusive and b) actually fucking works. And I don't know enough about the legal and practical implications to really usefully discuss implementation of policies which are extremely unlikely any time soon.)
