Its pretty easy for me. The whiners are the football team I despise the most. A tie for second between the cheatriots and seahags. The cheatriots for obvious reasons. The seahags cuz their players and fans are douchebags. Even though it was a 49er he dissed, I lost respect for Dickhead Sherman when he said that stuff about Crabtree on national TV in front of millions. That was bush league stuff.
There was a time the Cowgirls and Vikings were high on the list. But the years have softened me on them.
One thing to mention though, the whiners are the football team I hate the most. But the SF Giants are the sports team I hate the most. All those "Beat LA" chants and their sports station always promoting Dodger hatred just irks me. Their forums are filled with dicks that know nothing but hatred. Its like they enjoy a Dodger loss more than a Giants win. Its almost an obsession with them. Whats funny about that is, the Dodgers just don't seem as obsessed about the Giants as the Giants are about them. A lot of LA area fans hate the Padres more.
