I think I would completely ignore SUFC were it not for the fact that I live between the ground and the pub used by the nastiest supporters. It's hard to ignore when you are constantly aware of the risk to damage to you property and have caught football-related inebriates pissing in your garden.
Having said that, for a while I used to share a room with a guy who lived within the shadow of Anfield. You would expect someone in that position to either be a total fan or to hate football. Not this guy: he ignored it. It must have taken enormous force of will, but he did. Mind you, he also told me that he regularly had sex with his sister. Given the number of occasions I would return to our room to find him in bed with a succession of females, I have absolutely no reason to disbelieve him.
Takes all sorts.
