The impact of a story like this could be very damaging no matter how untrue. This is why we must keep our skirts clean! There must not be anything which could be construed as racially motivated.
There is a site which purports to have tea party signs. However, they inadvisedly have a poster which refers to “blacks”. There are so many weak points to the Democrat position that there is really no reason to go there. Anything said along these lines will be deliberately misconstrued.
The liberals will construe anything they like as being racially motivated - the truth be hanged. And the lie told often enough becomes truth.
