The subcategory is not to dilute the fact that it's incest, it's just to specify the type? Like, anyone who's reading twincest is very much aware that it's still incest lmao. No one's saying it's any "better" afaik. It's like how BL is a subtype of romance but I say I like BL specifically because that's the main kind of romance I'm into (this is not me saying incest is good, this is me explaining why subcategories are helpful for many people)
Oh in categorization yeah duh be specific but i mean either way its pretty weird in itself for people to actively search specific types of incest or avoid others. Like it’s gross and shouldn’t even be considered a romance. Its the equivalent of when people called killing stalking a toxic yaoi pairing
I know its fiction ??? and no one forced me to read it this was just me going back and reading old mangas i read as a kid and disliking it now because I personally think its gross ?? Im not going door to door on incest mangas preaching about the morality of it this comment was just me not liking what I used to read like 6-7 years ago

Jesus christ is anyone okay this isnt twincest, it isnt selfcest, ITS INCESTTTTTT!!!
I seriously dont understand why i read this in middle school but by god theres no justification to why two twin brothers BLOOD RELATED BTW! SHOULD BE IN LOVEEE???
