Racists–and those who exploit racism–are rarely about the business of openly declaring themselves as such, especially after their cause has been thumped, Before the Civil War, you could find all manner of Southerners exalting the "great moral truth of slavery." Afterwards, they claimed it was just "State's Rights." Before Reconstruction, the defeated Confederates employed explicit black codes that reduced African-Americans to slavery. After Redemption they moved to "vagrancy laws." "contracts" and "grandfather clauses." In the 1960s George Wallace would loudly declare "segregation forever!" Now we say "the Civil Rights Act destroyed privacy." In the era of militia madness, Ron Paul defended his racist newsletters. In the era of Barack Obama, he didn't read them.
It certainly is possible that Ron Paul never read a publications produced in his own name, just as it's possible to sincerely believe that the Civil Rights Act destroyed personal liberties, and it's possible to sincerely believe that if you are going to vote, you should be able to read the names of the candidates, or that Lincoln destroyed the original values of the republic. But it's also true that those beliefs have long been used to shield more odious ones. Forgive me for being suspicious when I see them employed in combination.
Fine. Just call them suspicions. Not facts.
