But I have tons of friends who are BSU fans. Like any group, they have their bad apples, but I think you could probably list the entire SEC ahead of them for "bad" fans just because the wingnuts in those fan bases go so above and beyond.
My biggest issue with their fan base is actually that they love to rag on other teams fans and talk about how bad they are. I swear, every team they play has the "worst" fans in CFB, including, not surprisingly, BYU.
