I think he was using hyperbole but I understand his point of view. You watch a show, you don’t like it, you don’t watch it again. Every now and then you browse for something, see it and think “I remember I don’t like it.”
Four years later you forget you how much you didn’t like it and go, “Meh, there’s nothing else on.”
I was that way with Hyperdrive, the BBC comedy scifi from 2006. I watched an episode 10 years ago and didn’t get even to the end of the first episode. Tried it again a few months ago and kind of liked it. It wasn’t great, but had several good episodes.
It wasn’t like hating Hyperdrive took up any part of my thoughts at all over the past 10 years.
Besides, even if it was part of the OP’s thoughts, how is fandom love of a fictional television show different than fandom hate?
