I think you're purposely being obtuse, Kate.
It's not "history" (per se) that us normal fans deride, but the Mouser's propensity to base his team's current worth and cache in the football world entirely upon it. If 'Pool was still winning things and terrorising the best sides across Europe, none of us would have any problem with you constantly bringing up the past, because your current form would fit hand-in-glove with it. But that isn't the case. 'Pool has had zero form for many seasons, now, yet you Mousers continue to dredge up past glories, and though your history is some kind of excuse for your current dreadful form.
Another large part of it, I'm sure, is that most ordinary footy fans feel embarrassed by Mousers. Imagine being in a room of foreigners and you are part of a small group of English blokes, and one of your number keeps on boasting, in a very loud voice, about the size of his cock; but everyone in the room knows that the bloke has a very, very small cock and - indeed - all the foreign blokes have cocks that are far, far bigger than the cocks of the English blokes. Surely to God, the last thing you'd want is some twat boasting about his cock!
Well, that's how us normal footy fans feel about you Mousers and your boasting about your Glory Days.
