I'm REAL LATE into this thread but wow, some of the best and worst posts I can remember in a long while. (dsearcy, yours was not a bad one)
Earl has a great deal of respect for and plays well with Buddy Hall, Shannon Daulton, Nick Varner, Allen Hopkins, Keith McCready, Jim Rempe, Kim Davenport, etc. Most of the guys from "his era". Believe it or not, he's on good terms with Oliver Ortmann.
Earl has had a feud with Corey in the past that's since been patched up nicely and they're golfing buds. He was at Archer's wedding to Melanie, as a groomsman.
He had a long standing battle with Charlie Williams that started over a patch that Earl took off and Charlie, as the head honcho of his own pool tour, banned him. CW also banned Corey Deuel and they'e still not exchanging Christmas cards.
Earl has had tiffs with John Schmidt, but I have no idea how they get on nowadays. Earl does not like Souquet, Peach, Immonen or Neils Feijen. Most probably because of the Mosconi Cup encounters.
And every other pro player has some peers he likes and some he does not like. Just like all us guys here...some members we like, some we don't.
Most every sport is the same. And classroom. And workplace.
