By engaging in it.. this isn't even a fig leaf, that's like posting insults and slurs to criticize insults and slurs, or saying "no offense, but $incredibly_offensive_thing". Even if that actually is the intention, that is irrelevant, the actions are what matters.
> A lot of fault must be put on Netflix for jacking up the controversy in their US marketing.
Nobody but the defenders of this even care about the marketing; it's about the content, about the minute long close up shots of children "grinding".
Regardless of the attempts to frame it that way, "thinking of the children" isn't just a monopoly of hypocritical, puritan "outrage", it's also what any healthy adult does by default. Even (non-predator) animals in some cases treat the young of other species that way.
