I think people no longer understand that "viewer discretion is advised" does not mean "vaguely bad content ahead," it means View At Your Own Discretion. As in, if you see the content going in a direction that is unsuitable for you in any way, it is your responsibility to stop viewing. Don't blame creators for your failure to listen to your own warning signs. Nobody is forcing you to finish the episode, the chapter, the sentence. That's all you.
