That's one thing PhantomStrider constantly makes a point of when reviewing XYZ kid's flick or show; content aimed at kids, and in general, shouldn't talk down to them like they're stupid like, say, Dora does.

Language like 'unalive' when referring to killing, for example, even in a totally legitimate manner taking on some inherently dark subject matter like with any True Crime stuff, could be construed as talking down, vs. just presenting the content straight-up and being as accurate to the subject matter and as respectful to the audience which might very much include the families of the victims of whatever crimes are being covered, as humanly possible.

Like imagine pulling up a video essay on someone like Jeffrey Dahmer and having it be littered with language like 'unalive' and 'grape' when dealing with very, very serious subject matter like that, if I happened to be a family member of one of that guy's victims, I'd feel very talked down to and be insulted as hell, plus it's just not good optics to use language like 'unalive' when the subject matter you're dealing with is very dark and serious subject matter.
