Fans of both are insufferable. They feel they are entitled to win. But at least Ushited had a reason to feel that way, as far as a reason is possible.
So I guess I should hate Liverpool more, but I don't. I hate Liverpool slightly less, as Utd will always be our rival club. Our nemisis. They could sink to Division four, and hopefully one day they will, they'd still be number one rival / grudge though.
Once upon a time I found it amusing when Liverpool got a one-up over certain teams (Utd, Chelsea, AFC, Everton). Their fans have gotten worse and worse each year and that's gone out the window.
