I hate when people review fan fic just to say “I prefer X ship but this was cute” I literally don’t care what ship you prefer. Just say “this was cute”. Why do you need to tell me you prefer another ship? It doesn’t matter at all. And no, I’m not one of those people that takes it as a compliment that you found whatever I wrote cute even though you prefer a different ship.
It sounds rude as hell when you do that because you know what it sounds like you’re actually saying? It sounds like you’re passive aggressively saying “I think you wasted time writing this because if you had written it about a different ship it would be better, but this was still okay I guess”. Maybe people don’t even realize this but that’s what it comes across as? So don’t.
The last thing I posted that got this comment wasn’t even a ship I like that much (because it was a request) and it still pissed me off. If you prefer X ship then either don’t read it, don’t review it, or just leave out the fact that you prefer a different one. I put at the top of every chapter what the pairing and prompt is so it’s super easy for you to skip it if you don’t like it. :)
