A list of the teams I hate in order of level of hate:
1 - Dodgers.
2 - Yankees
A's used to be here, but now that I have to put up with everyone in NY's bullshit, the Yankees have actually come surprisngly close to the Dodgers in terms of level of my hatred.
3 - A's
With them in the Bay Area they create an unneccesary competition for attendance, they beat us in the World Series I attended, their fans piss me off, they play in a crappy stadium, and they want to move to San Jose. I don't want a competing team I hate in my hometown. Plus the American League is gay.
4 - Braves
The best regular season in recent memory (1993) was spoiled because of the Braves. I hate Bobby Cox, John Smoltz, and I hate their cocky attitudes.
5 - Angels
They're in the OC, which sucks, and they beat us in our most recent World Series. That Rally Monkey can lick my balls.
6 - Red Sox
I don't really know why I hate them now. Maybe it's because they win. I basically think they get too much press and play. I love Wakefield though.
7 - Marlins
They have kicked our asses in the Division series twice. Both teams were mercinary type teams that sold off a lot of their talent at the end of the year. They're an expansion team. They don't deserve two World Series rings.
8 - Padres
I really don't hate them. They just annoy me. They think they have a rivalry with us. They don't. They think they have a rivalry with the Dodgers. They Don't. They just think they are more important than they really are. No offense to Tony Gwynn, but the Padres and their history are worthless.
9 - Diamondbacks
I actually rooted for the Yankees in the 2001 World Series. I was pissed when the D'Backs won on a bloop single off the best closer of that year. Again, they are too young to receive a World Series ring. It's a bastardization of the game to have a team that is less than 5 years old to win a World Series over the most storied franchise in the history of pro sports. But, we OWN them everytime we play them, including back in the first Randy Johnson era.
