From Andrew Breitbart's attack on Congressional Democrats for walking outdoors:
The first sign that a plan was in place was the ham-fisted, high-camp posturing of the most controversial members of the Democratic caucus walking through the peaceful but animated “Tea Party” demonstrators on Capitol Hill.
Emphasis mine, because Breitbart's use of the word "controversial" as a stand-in for "Black" pretty much tells you all you need to know about Breitbart and the right-wing drive to blame Black and gay congressmembers for going where angry White people could see them.
(This is the same school of thought in which "carefree" kids are ones who aren't gay and don't know about anyone that is)
Unless we're supposed to believe that two-term Rep. Andre Carson became one of "the most controversial" Democrats based on the content of his character.
