Yeah, it sounds like a solid policy, not to get down on people for Doing Multiplicity Wrong.

But I'd criticize this one for plain old-fashioned Doing Family Dynamics Wrong, with a coat of multiplicity terms painted on top. The idea that all families must fit into a specific mold, that one person gets the final say in all decisions rather than having it be a cooperative effort between adults, and that the final-say person is destined by biology, who cares about the individual talents/abilities of the people in each specific family...just Bad Vibes all around.

Ooh, wow, that's recent. Here's hoping she, and whoever else she had around at that point, are at peace now.
