Weird flex but okay, you are aware that trans (and even nonbinary) people exist in reality right? I myself have a number of friends who defy the binary.
You're allowed to not be interested in the fantasy trope version of that, but it might be a more productive use of your time to read stories with themes you do like, rather than seek out something with the genderswap tag plainly in view, I know that I just blacklist themes I don't want to see when doing searches on Mangadex, helps keep my blood pressure down.
