Okay ship whatever the fuck you want on your own time but don't get angry if it's incest and people are uncomfortable with that. Because they should be. And it sucks when incest ships are shoved down our throats. It's one thing to not like a ship just because you don't see it, and it's another thing not liking a ship because there are genuine problems with it.
And it's also not something that should be taken lightly, incest is disgusting and harmful and it sickens me how accepted it is in this fandom. Don't say "oh well why can't you just let people ship what they want without bothering them" because it's insulting to those who have gone through incestuous situations themselves when you fetishize it. It doesn't matter if they're fictional, normalizing it isn't okay.
This also applies to abusive and pedophilic ships.
