Not sure where to start here....Are you saying the NAACP is suppose to collectively be a "Moderate" group? If they have an overwhelming political lean, as is the case here, I'd say the reaction in question would be normal in a group setting...What if someone pulled out their "Muslim prayer rug" in a Christian church in the middle of a sermon and started praying, I'm sure they'd get a reaction too....
Imagine though if on an individual level, a person REFUSED to simply shake another's hand in greeting just because of their politics, now that would be personal, classless, and newsworthy...Now I know something like this happened recently, I just can't put my finger on it...
