In alphabetical order, things I hate about each SEC team's (including UT's) fans on the net:
Alabama: Online Bama fans are more consistently filled with animosity than any other SEC team's fans. They truly think the world is out to get them.
Arkansas: Too melancholy. Chin up, guys. Easily freaked out, too. Mustain, anyone? Everybody on Earth knew, at least subconciously, that the kid would be a Razorback.
Auburn: These fans are Al Gore-level bitter about being left of the 2005 Orange Bowl. Let it go, guys. There is no written rule anywhere saying going undefeated in the SEC gives you a spot in the national title game.
Florida: These fans think everybody hates them a lot more than they do... Guys, your program is still a young'n in terms of success levels. People hated Spurrier, not Florida.
Georgia: Like Bama without all the Bear Bryant jokes.
Kentucky: When it comes to football, how can you do anything but pity these guys? Seriously. You just can't hate them. All you can do is chuckle while they huddle up in the stadium, half the fans in fetal positions saying hail marys that they can fall into a coma until basketball starts (how's this season going for ya?)
LSU: What a bunch of drunken idiot losers. GUESS WHAT GUYS?! YOU ARE THE ONLY PEOPLE IN THE COUNTRY WHO THINK YOU WON THE 2003 NATIONAL CHAMPIONSHIP OUTRIGHT!

Plus they are the only team I've seen that will barely scrape by an opponnent (see: vs. Oregon State 2004, vs. Arizona State 2005) and act like it was a complete beatdown.
Mississippi: Don't see many Rebs fans on the internet... I've heard you guys throw a bitchin' party, though. Props.
Mississippi St.: Oh yeah. You guys play football, huh
South Carolina: After Spurrier's first season there, South Carolina may very well be on a ride to the upper echelon of the SEC East, and they're laughing in our faces all the way up... Screw those guys. They're the new Florida.
Tennessee: This one is hard for me to get out... But let's do some introspection guys. It's not like internet Tennessee fans are without our flaws. Let's face it, our squad is a player on the national level a lot less than we'd like to believe. We're usually just decent but never great... Fulmer needs a few more SEC titles and BCS bowls before I'll reconsider.
Vanderbilt: Yeah, you're the smartest people in the SEC. Blah, blah blah, too bad books can't play football
