My hate is cyclic, and for the most part it has more to do with the Bills level of competence than other teams, specifically. If they were a better team I'd have stronger feelings about their competition.
I've lost my contempt for the Dolphins, and now view them with mild disdain mixed with a sense of irrelevance.
Hate is too strong of a word for what I feel for the Jets, but dislike is not strong enough. I hate them less when they're inept, then I find them more amusing.
I abhor the Patriots* and have nothing but contempt for them. Their success is almost as painful to watch for me as is the Bills failure. When they first started winning I had a begrudging respect for them, but with each cheating episode revealed, as that respect was lost, I would sooner root for the Goodyear blimp to fall from the sky and crush them than see them win another Super Bowl.
Most of the rest of the AFC has annoyed me at one time or another, namely Pittsburgh and KC when the Bills were a real team. I don't particularly care for Denver. I used to dislike the Raida's, but until the Bills are up to the task I'm kinda rooting for them because of Khalil Mack, though I find Carr's eyeliner effeminate.
I wish I could hate the Titans, but it's not their fault our kick coverage sucked on that play, illegal forward pass or not.
I hate the Cowboys because I have a soul. My hate for the Redskins and the Giants is all but gone. I'm working up a hatred of the Seahawks.
As for other rooting interest, I have a mild passing interest in the Lions and the Texans, both cities that I've lived in or near and whose fanbases I've felt a kinship with. I used to like the Saints before they won the Super Bowl, and since I'm dating a New Orleanian and have moved to the area, I'm trying to find that again...
