LSU fans in general?

Last night was my first SEC game which was the LSU vs. SC game. Being a graduate from Clemson, they are my fav. but I almost went to LSU for grad school, so I root for them in the SEC. A USC friend of mine let me go to the game with him and we sat beside the vistors (LSU) section.

It was my first experience with a group of LSU fans and was severely disappointed. I witnessed some of the most rude, profane, selfish, disrespectful, and maliciously hateful behavior of any group of people I have ever seen? It wasn't just a select few, the majority of the LSU fans I saw were acting in this manner?

I felt pretty sorry for my in state rival friends, the onslaught lasted throughout the game. It was a big letdown to me personally. As a Clemson fan, we lose quiet a bit, especially this year, but I have never seen treatment of another team's fans anywhere close to this. No even from the instate rivalry game.

2 questions:

1. Is this type of behavior pretty much the norm for LSU fans in general?

2. Is it cultural or just specific to the traveling, away game fanbase?
