It’s like asking “Does anybody dislike cartoons and comics?”

I have to disagree.
Comics is a huge, world-encompassing category of media in which events & stories are depicted through (generally) simplified art with text insertions. Manga (for example) is a subset of comics, being both specific to a single country as well as existing as a certain style of comics.

Personally I'd add that manga tends to exist under fairly tight conventions in terms of how things are visually portrayed and in terms of how information and context is given towards the reader. For example, kind of like emojis, there's a bunch of facial reactions and certain simple phrases that instantly tell you what mood or reaction a character or the author is trying to impart. This kind of thing isn't surprising to me either, as Japan tends to heavily codify cultural tradition, even in a relatively new-ish field like manga. There's also the fact that an enormous tradition in manga came out of aping or riffing on the early creators, primarily Tezuka Osamu I'd say.

So, point is-- one can dislike a certain niche or branch of comics, but that certainly doesn't have any special impact on how one likes comics in general. Personally I'm not a huge fan of manga, and superhero comics bore the tights off me, and I'm not as much a fan of underground comics as I used to be, but overall I'm a huge fan of the comics medium, and of course love me some BD, part of why I try to make a new post daily.
