I actively encourage all ship art, even if I don’t care for it. No matter how sweet or how depraved the ship or portrayal is.
If someone wanted to draw Cassandra (28) getting inappropriate with Hazel (12), well I wouldn’t personally care for it but hey - you do you.
Honestly I’d really only object if they made the ship art something sociopolitical or tried to insist that the characters were whatever sexuality they felt like projecting onto them - like, canonically, not just for fanon or an AU type deal, no matter how much evidence there was to the contrary.
That and any Polyships. You can do it, but I’m gonna ignore it and frown upon it due to personal squick. I won’t say you can’t do it tho.
I want people to have fun with my characters, I just don’t want my characters being used as mouthpieces. That’s what I can’t stand. But I encourage people to do shippy stuff. Otherwise I’d have to do it myself and that’s just gonna take up too much time.
