Here are some other assorted "racists" and "bigots" and people who are "disrespectful", because they didn't accept Obama's invitation to the White House:
Dan Hampton (member of 1985 NFL champion Chicago Bears)
Greg Biffle, Kurt Busch, Carl Edwards, Kevin Harvick and Tony Stewart (NASCAR drivers)
James Harrison (member of 2009 NFL Champion Pittsburgh Steelers)
Here's a list of people who refused invitations by REPUBLICAN Presidents (they, of course, are great Americans who were practicing their "freedom of speech" rights):
Joey Porter, James Harrison, Tommy Maddox (members of 2006 NFL Champion Pittsburgh Steelers)
Manny Ramirez (member of 2007 MLB Champion Boston Red Sox)
Michael Jordan (member of 1991 NBA Champion Chicago Bulls)
Larry Bird (member 1984 NBA Champion Boston Celtics)
I won't even try to list all of the "non-athlete" people who declined invitations to the G.W. Bush White House.
