I said society shouldn't tolerate impregnating 10 year olds just because it's some tribal tradition.
And what form should our intolerance take? I don't think it's tolerated because it's "tribal tradition", I think it's tolerated because part of how we and other countries reconciled the fact that our nations were built by stealing land from other people is that we reserved territory for them and promised self-governance, which we enshrined into law.
It can only be statutory rape of a ten-year-old if there's actually a statute that applies to these people. Since they're an indigenous people on a legally self-governing reservation - correct me if I'm wrong about that - there doesn't seem to be.
