You can ship what you want. But you can't automatically expect it to be cannon, and if it isn't made cannon don't fucking harass the creators. Don't start stupid petitions. Don't harass those who like the cannon ship. Just accept it. Even if it's non cannon it's okay. Just go enjoy your ship.
Would it be appropriate to have my altar to Aphrodite in a fish tank and then in a plate next to it be like an offering plate? (My parents are very christian) and also, how would I give a petition to aphrodite? I know it's different for some dieties
