The Paul family is not racist.
The current CRA escapade is not about racism.
However, unfortunately, in the early 90s, a philosophical movement (paleoism) headed by the likes of Murray Rothbard, Lew Rockwell, and Pat Buchanan (none of whom are racists) did pander to white racists and survivalists. Some of these racists propagated their own views under these paleo affiliations such as Chronicles Magazine, the Rothbard-Rockwell Report, and the Ron Paul Survival Report.
