The thing all these think pieces have in common is they all go on about what will be better for society but never what's best for the individual children.

The trouble is society is a cultural concept, it doesn't really exist. Its only expression is in its individual members, which are very real.

We know what is best for kids is to be raised by their biological parents in a stable family.

If you harm the outcomes of individuals en masse to try to level everyone then that is how you hurt society. Everyone might be equally but they'll be equally in the shit.
