Do you live in the Bay Area? It makes a big difference, especially if you're not a fan of Bay Area teams. Raiders fans are definitely dicks, but I at least respect the fact that they're head over heels for their team year after year, regardless of whether they're good or not. They haven't been good in a decade, but their fans still wear that team on their sleeves. The 49ers, Giants, A's and Warriors' fans though? I almost thought those teams moved cities. Nobody claimed em until they started winning Lol. The thing I hate the most though, is the large block of Bay Area fans who are Raiders/Niners fans, or A's/Giants fans, depending on who has a better shot at winning the championship that year.
Sharks fans are pretty loyal though, but they're unfortunately from the Bay Area, and my hatred has grown enough to spill over into their camp.
