I've genuinely thought about this so much. I feel like it's also sort of a self-fulfilling prophecy cause then most of yaoi ends up being very cliched/stereotypical romance, which leads to people judging it even further, which means seinen authors are less likely to put yaoi elements in their work.
i wonder how many "seinen" and "shonen" authors wanted to write a story that had BL elements but couldn't make their characters' relationship canon bc it would just reduce the story to “yaoi/BL” and they wanted more people to read their story without the prejudice that comes along with tagging a story as BL. i definitely think jjk, berserk, evangetlion etc. would definitely get a BL tag.
