> People can horribly misuse the phrase "comprised of".
I think that phrase is always incorrect. I suspect the problem is that people aren't used to words that take a list as their direct argument, like "comprise".
Wikipedia leans heavily to descriptivism (as do nearly all lexicons, these days). So there's no incorrect usage; there's only usage that jars, for some people.
I don't go around telling people they're ignorant because they can't speak their mother-tongue properly. That would simply be rude. But English text intended for publication should be correct English; it shouldn't be garbled, whether because it's written by a non-native speaker, or a native speaker who isn't well-read.
That implies that there is such a thing as "correct English". This seems obvious to me, but that's exactly what descriptivists deny.
Let's not get into whether "literally" is a synonym for "figuratively".
