Poll: Wearing your team's merchandise to a game they're not playing?

This is something I always think about. I live in Miami and go to a lot of Marlins games. I'm a Red Sox fan, but I'll usually wear a Marlins' cap or something to be kind of fit in with the crowd. I always thought wearing Red Sox gear to a game they're not playing in would be kind of disrespectful to Marlins fans in their ballpark. Despite this though, you go to a Marlins' game, and I bet you can find a cap of every team in the majors. I wanted to hear your thoughts on this and ask if you've ever worn your team's merchandise to a game they're not playing.
