the current President, it is safe to say you must be a racist? Surely you aren't.
First, they were not "opposing the President", they were shouting in draw attention to their agenda. They were there to take advantage at a high-profile event, but seem to not been aware of the President's stance which he had articulated in the past.
But you chose to spin it to suit your own agenda--- show that people are against Obama.
The accusation of racism has no basis in fact, but appears to be in retaliation for the accusations made against the T-P that racism has motivated some to join that movement, like the Dixiecrats of the ppast which was the strongest in the South.
