If I get well what @tired_programmer is saying, the issue is not about accepting other people's taste, but rather what it means about her comic that people who like it AND like some other comics that she think are really bad.
I personally think it means close to nothing in relation to your comic.
There are a lot of possibilities for people to like various qualities of comics, and every reader will have their own explanation.
There may be a few readers who just have low level of expectation and comment favorably on a lot of comics.
There may be a few readers for whom it's very important to support every creator they know, regardless of quality (if these ones comment in a constructive way, even if it's all positive, they are actually valuable commenters).
There may be a few who genuinely care about these works that you find bad, because they see in it something you can't see. I'm sure you can think of a few works that are unpopular and not that great overall, but that you feel a special connection to for a very obscure reason, that is unlikely to be shared by many).
There may be a few who are simply very early in their voyage through comics. Either young people with not fully developed tastes and standards, or simply people new to webcomics. I know my tastes evolved (and refined) immensely in the first few months after starting reading webcomics, and I was 37! Imagine a 14 years old...
Plenty other reasons I can't think of, I'm sure.
