In general I'd say teams that attract glory hunters, and semi football fans(those that don't really follow football on a weekly basis like most of us here do) would have those kind of fans. So for example, where I'm from, it's not common to find fans of a team other than Barcelona and Real Madrid, those who support a team other than those two tend to be quite knowledgeable fans in general. The most deluded fans I've seen have been mostly Barcelona and Real Madrid fans. Obviously on internet forums, some of the EPL fans are quite bad, especially those that are British and don't follow football outside the UK.
