Why did the Tea Party Take Down the Billboard?

We have watched many Teabaggers promoting racism for the last year and trying to hide it by calling anyone who mentions it a "racist." Now that they are feeling the heat and the truth is coming out, they are trying to hide their immoral agenda. Radical conservative activists can only win if we buy their lies. If there aren't violent racists in the Teabagger movement, why is the NAACP receiving death threats for calling out the violent racist Teabaggers?
