So it boils down to this: either Ron Paul had no idea what was being written in his newsletter over a five-year period, and when he was asked about it by the newspapers, he chose not to deny that he wrote them and deliberately allowed his staff to believe that he wrote them, or Ron Paul wrote those articles in his newsletter and then later realized that by exposing his own racism, he might well cost himself any real chance at the White House.
Lastly, I'd like to refer Ron Paul supporters to a real liberatarian, Dave Nalle, head of the Republican Liberty Caucus, who had this to say about Ron Paul:
[Ron Paul is] an inflexible ideologue who subscribes to a variety of extremist views which would make a terrible basis for national policy. His interpretation of the Constitution is highly selective. He seems not to recognize terms like "public welfare" and "common good" and rejects the long history of constitutional scholarship and jurisprudence on which most law is based. His understanding of the economy is based on fringe economic theories which most serious economists do not consider credible. As for foreign policy, it's an area in which Paul has no experience at all and his foreign policy would basically amount to isolationism which would have disastrous economic and political repercussions.
[Ron Paul supporters] completely overlook Paul's support for the reactionary conspiracy nuts at the John Birch Society and the reprehensible 9/11 Truth movement or the fact that he raises money on white supremacist websites and has the endorsement of racist leaders like former KKK Grand Wizard David Duke, White Aryan leader Tom Metzger and Stormfront Fuhrer Don Black.
I should note here that I owe Dave Nalle an apology: I accused him repeatedly of being a Ron Paul supporter, and I was obviously wrong. That said, Mr. Nalle and I agree on very little, but we're apparently in complete agreement that a Ron Paul presidency would be a very, very bad thing for America, and that if Ron Paul's not a racist, he's certainly doing his level best to make us think that he is!
