I think that the main boundary is between deciding what you like versus what others should like.

The former is fine; even if someone like "ahneemay" because it's trendy, or avoids fanservice or because the person got tired of [whatever they're watching in USA nowadays, I seriously do not know] and wants something different.

The later however is not. It's just someone being entitled, and expecting people to appease their personal tastes. It doesn't make them just a shitty anime fan, it also makes them a shitty person, unable to deal with the fact that the world does not revolve around their belly button.

Just my two cents.

maybe just as annoying as fans who complain about tourists

but even known figures in anime like miyazaki, tomino, and hideaki anno criticized things like fan service

Americans

well im glad im not american. where i live we just watch what we like and that's it. its just entertainment

Filthy Frank: "uh uh wheare aeur the subtituls"

I assume 'tourist' (in fandom spaces) got started in someplace just awful, but it's a really nice word. I've always felt that being s casual fan of something was perfectly normal, so tourist is far more useful a word to use. I'm a casual fan of scifi and i wouldn't go around making demands of the Aurora 4x devs/community or something, but a tourist would.
