LOL damn bro, the fuck you "hate" so many teams for? Care to give us a breakdown?
I hate all of the NFC North and East, the cities, the players, the team names, the fans, etc. Pretty hard not to. Some more than others. Vikings, Lions, and Skins are on the low end while Packers, Cowboys, and Bears easily rank in the top 5 of most hated teams in the NFL. In fact they would be top 3, but the Patriots bumped the Cowboys and Bears down a notch to numbers 3 & 4 respectively.
Seahawks and Titans are just gay. The impression comes from the players, coaches, and fans mostly. (reference that reasoning for the gay comment in future examples)
Patriots - too many obvious reasons
Broncos - Deep hatred for John Elway from youth added with Chiefs and Chargers being on the more favorable list (favorites of the AFC).
Cubs - Chicago, band wagon "fans", future Red Sox type fans - see below, etc
Yankees - pretty easy to hate, New York, band wagon "fans", etc
Red Sox - Boston, band wagon "fans", legit long time fans who were losers now arrogant gloaters, etc
White Sox - Chicago
Angels & Rockies - gay
Braves - fuck that whole tomahawk chop shit
Lakers, Kings, & Celtics - hated them growing up & hate their modern incarnations
Warriors & Kings - gay, fans, losers, dislike their players past and present
Spurs - hated growing up
Nuggets - gay
Jazz - always hated, hate the city, always hated the players, Malone & Stockton = weak
Trailblazers & Sonics - gay
76ers - only liked them for a time because of the round mound of rebound, once he left only thing left was to hate them, never liked AI, never had a reason to start liking them
Cavs & Pistons - hate their cities, never liked their players, never given a reason to like them
Pacers - Reggie Miller, nuff said
Magic - hated the shaq and the penny, never got a reason to like them
Bulls - Chicago, hated them growing up, distaste for Jordan, Pippen, and crew
Some of those teams have legit spots on the hate list because they play against teams I favor. A lot of them come from people being "fans" for no good reason. Hate those people for being fake sports fans which then gives me a better reason to hate the team than their "fans" for liking them. Guilt by association. Lame fans = lame team.
