It is my personal opinion that people who dictate who is or who is not a “true fan” based on that fan’s personal preferences is not a true fan. People should be able to ship whatever the heck they want. Not everyone loves GerIta, UsUk, FrUk or other popular ships. And there is no proof that this pairing is ‘canon.’ I could just as easily throw an arguement against it and it would have just as much backing as your arguement for.
So ship what you want, but don’t go shitting on someone else’s cherios and telling them they’re not a "true fan" for not liking the same pairing as you. Because in my opinion, that makes you a raging asshole.
