Carlos Delgado's protest (ESPN.com)

Carlos Delgado has been staying in the dugout for the playing of God Bless America at baseball games because he does not support the US war in Iraq. Delgado also opposes "the Navy's presence on the Puerto Rican island of Vieques, which the Navy used as a weapons testing ground for 60 years."

The ESPN article draws parrellels to Mahmoud Abdul-Rauf, the former Denver Nugget, who didn't stand at attention during the national anthem. Delgado's protest obviously isn't at the same level as that but it still will likely draw harsh treatment from some US fans.
