If conservative organizations were handing out protest flags to make them look more extreme, the MSM would pick right up on it... If a few hundred thousand showed up at some leftist freakout, it would be BIG NEWS - with us it was nothing. Bias and hatred on the part of the MSM...
What DOES matter is that viewers recognize the bias and stop watching. Or, better yet, they switch over to FOX.
If we want to get the attention of the MSM we could do like the football fans do: Make cutesy signs that incorporate CNN, PMSNBC, CBS/NBC/ABC/FOX in the sign.
