Let me say this (and trust me, it's REALLY hard to do
).
As a tour guide at Camden Yards, I get a LOT of Yankees fans. I have to say that they are my favorite people to take on the tours. They are knowledgable about their team and baseball in general, they like a little back-and-forth trash talk (hey, I have to have a little fun
), and they are great tippers.
Sox fans are like that too, only to a lesser extent.
My problem comes from what happens when you mix the Yankees, the New York attitude, and alcohol. That's where 99% of the "classless Yankees fan" comes from. When they are sober, they can generally keep it civil.
