For me, because I grew up listening to City on Humberside, Saturday afternoon & as someone was talking on the sports show, they had a little jingle, “and it’s there!” Crowd noises. It meant one of the local games had a goal, it always excited me, but then it would turn out to be John Tonder saying Clive Mendonca had just scored for Grimsby, but it did make me a little interested how they did & Scunny, so don’t have that real hatred.
I used to hate Scarborough when they kept beating us, but again have a soft spot for them, being where I lived for a few years, the way they went out of the league & subsequently went under.
So my teams I don’t like is Leeds, Wednesday, Sheff U, Liverpool & Chelski. For different reasons, not rivalries.
I class rivalries as a team we play regularly, but don’t really hate as such.
