I understand why people feel this way. There are lots of reasons! Neurodivergence, so much effort put into one thing, having great recollection, etc etc. I feel a bit like that too, sometimes, that I know best,

umm but then I remember that's made up and utter nonsense, because while I may be able to know best (from my perspective), it is just that—from my perspective, and someone else can respectively be the #1 fan or whatever in their own right. And that's great I think.

I also understand why, for whatever reason, you wouldn't wanna hear what others have to say about your thing. Many such reasons. But I personally believe it to be good, to listen, and consider, because there are so so so many um...views out there, that you won't realize you're missing, until you hear them first hand. And you know what! If they're completely "wrong" then it's so fucking funny! And you can feel a bit righteous or whatever. Fun and games for real
