A Raider fan got shot at a Cardinals pre season game in AZ last year, does that make them rivals? lol
Like I said numerous times, it ain't even a rivalry amongst fan bases, it's a rivalry amongst -some- of the fans. Not even everyone in the bay argues about this shit only -some- do, it's a percentage of a percentage of the fan bases.
People from the bay got a big ass ego apparently, all like "my co workers from the bay make fun of the raiders, so that means the entire fan base is our rival" lol
