Can't stand Hogan: Vince Russo
Vince Russo claims to be a life long wrestling fan, and in fact even trained for the ring though his small stature and lack of athletic ability led to his career going nowhere.
He got a stroke of luck by writing a letter to WWF magazine in the late 1980s. Linda McMahon was so impressed with his letter she hired him to write for the WWE's publications, including the magazine and programs. Russo adopted the pseudonym Vic Venom for his articles in the magazine, and often used an acerbic wit to lambaste talents he didn't like, usually the babyfaces.

He would eventually parlay this into joining the WWE creative team, and was named the head writer for all of WWE's programming. It was Vince Russo who heavily pushed the partial nudity, sex, and violent themes that were a hallmark of the WWE's Attitude Era.
Money talks, and WCW--flagging behind in the ratings after WWE after nearly three years of dominance on Monday nights--offered him double his salary to join Ted Turner's promotion. Russo agreed, and began to make heavy changes.
One of the things Russo disliked about WCW was that the veteran talents like Hogan basically got to book themselves. He set out to push younger stars instead, and this wound up with him butting heads with Hogan. It led to the famous moment in WCW history when Jeff Jarrett simply laid down for Hogan and allowed himself to be pinned. Russo came out, breaking kayfabe utterly, and called Hogan a 'piece of s**t' and assured fans they would never have to see Hogan again.
This led to a lawsuit filed by Hogan against WCW, and eventually Russo was removed as head writer. The two have managed to be civil enough to each other when they met in TNA, but the waters are still pretty iced over.
