Because they’re outdated and no actual gay person uses them. Plus those terms are objectifying, as they’re used to label characters based on what position they like to be in when having sex. If you want to use correct terms, you can ask who the top or bottom is, but even then I don’t think it’s good to be analyzing and trying to label characters based on what position they like.

uke/seme are Japanese terms that are only used specifically in BL manga made by women, but actual gay people do not use it in Japanese. If you wanna know what they actually use, the real terms they use are, neko for bottom and tachi for top. Then riba for switch. These terms are used both by both gay and lesbian Japanese people.

Bruh it’s a comic book. No one in their right mind is gonna be asking about people’s sexual preferences in real life. I repeat “No one in their RIGHT mind”. Other people’s sexual preferences is not anyone’s business but a comic book is a comic book. We follow their entire life, trying to figure out a characters sexual preferences is only a tiny bit of information about a character, like knowing if they have some kind of kink. That being said some idiot is probably gonna think that it’s okay to do it to people. So I see your point

I think the general context of the question is some people are wondering who is the “man or woman” is in the relationship, which is moreso implied with the use of uke/seme. I also know some gay comic creators have been uncomfortable with people asking who’s the top or bottom is of their characters. People wonder who the top or bottom is as if they can’t be switches, as if there has to be the “uke” or “seme”. It’s less weird if you are curious if they could be switches as well. But I know some people want there to exclusively be a top and bottom
Does it matter who the “uke/seme” is? Not only is it a creepy question, those terms are gross.
