I agree with this... Personally I never want to see the Yankees win... although, I have to admit, this current Yankee team I do not feel any particular hatred towards, maybe because of the young home grown talent. I do have a lot of Mets fans buddies who know a lot about the Yankees and will actually watch their games rooting against them. I just like to check the box score in the morning and see that they lost, or will root against them in playoffs
When you are a fan of the better team it is easy to not hate on the other, like the Jets... in general I wish them well and would be happy to see them host a ticker tape parade someday (it is fun to laugh at them when they are acting like the Jets) but most Jet fans HATE the Giants
