I think the problem with the trope is more than just whether it is just a Anime and Manga thing.
The big problem is "What does this mean"?
"Any person with bushy eyebrows" with sounds rather like "Any person with blue eyes" and is pretty much Not a Trope
Is there supposed to be a link between bushy eyebrows and a character type? If so, is that link only present in drawn media, or can you also have written descriptions that make the same link?
Is this supposed to be "In the same work, men are consistently drawn with thicker eyebrows than women as a form of gender identification"? If so, everything that isn't a drawn medium needs to be cut. Also, all the examples need to be redone to talk about works as a whole and not individual characters.
