You can divide the people of the world into groups based on any aspect of life that you want, gender, race, religion, nationality, hair color...and you will find that fairly consistently, about 10% (give or take) will be _______s. Unfortunately, that goes for Steelers fans as well as it goes for fans of every other sports team on Earth. I know or know of many Steelers fans that are an embarrassment. But 90% of them are great people as are 90% of the fans of every other sports teams on Earth.
On a side note. I have always liked the Packers as my unofficial "second" favorite team in the NFL...so I would like to see them go the SB, but in the end, lose to the Steelers (fingers crossed that they make it.), or the Jets if it is them that go...AFC has to win in my book as (I think) the AFC is behind by 2 Superbowls to the NFC.
