Like the so-called mother of the "Princess Boy", these people should have their children taken from them, and they should be imprisoned for child abuse.
Instead, Western culture lauds their open-mindedness.
Sure, there's a firestorm. But it is in the context of a "discussion" of the issue, rather than an emergency response to child abuse. An entire segment of society believes these people are doing the right thing, and that segment is supported by society's institutions meant to protect children.
