Most sports fans suck, I think that's a fair statement. However some teams undeniably have worse fanbases. For instance Notre Dame and Duke fans are unquestionably some of the worst in the country. NATIVE New England Patriot fans are fine, just as many Red Sox fans aren't horrible. It's the bandwagon fans in different states who suck. Celtics fans are pathetic tho, whether they're from Boston or not.
LA Lakers fans suck. University of Michigan fans suck. Ohio State fans are pathetic pieces of shit. OREGON football fans are pathetic.
On the contrary, Green Bay Packers fans are cool. Most Detroit sports fans are passionate and don't bandwagon jump. I respect Cleveland Browns fans, and Chicago sports fans who passionately put up with bad teams.
