I get that, but for one, that's more than 17 years ago. For two, it's not like it destroyed the one and only chance the Rams had at winning a Super Bowl.
I was once a Bengals fan, and I certainly didn't hold a 17+ year grudge against the 49ers after they stabbed child me through the heart in January of 1989. I will remember the moment forever, but I didn't hate SF forever. The real lasting memory is anger at the Bengals for the 90's, not saltiness against the 49ers. My own team took my born-and-raised passion for professional football and raped me nearly to death with it. Since you're a St. Louis native, I'm sure you know that betrayal from your own team is much more painful than anything another team can inflict.
Like Falco Lombardi said, they're loathed here because of that Super Bowl. The GSOT never recovered, and it basically plunged us into the dark ages that lasted until McVay's hiring. So, right or wrong, that's why I can't stand the Patriots.
