Pride, like most emotions or feelings, exists on a range. You can be proud of all of these things, including your achievements; it's the degree to which you carry that pride that determines the "douchebaggery," don't you think?

The sports team, I would say, probably has the lowest "douchebaggery threshold," as the spectator is so far removed from the team—especially for professional teams—whereas the others carry more involvement and/or stake for its community.
