"This is the franchise that pretends to be classy, and yet the Niners fanbase consists mostly of your standard Bay Area hooligans, who rock goatees and
rape grandmonthers in wheelchairs in the parking lot. Many Niners fans are simply Raiders fans working undercover. They're just as violent and miserable, and they deserve to have their entire franchise shuttled out 50 miles south to Santa Clara, where they can't hurt law-abiding San Franciscans. The rest of the fanbase consists of transplants who go to the Niners game just so they can network with someone they found on LinkedIn. OMG THIS STADIUM HAS NO BIKE RACK! (designs app that gets recommended in Wired but is used by no one)
Niners fans are unique in that they are both spoiled AND disloyal. This team has won FIVE Super Bowls, and even that wasn't enough to keep people hanging around during the Singletary years. Hell, they could barely tolerate Jeff Garcia taking them to the playoffs. No no, this team has to average 13 wins a season to get natives to actually look up."
