Ron Paul walks out on CNN interview about his racist newsletters
Back in 1995, he thought these were classics he was producing, and even considered them "educational". With the kind of opinions he was espousing/publishing, I wouldn't consider them that even in terms of finance. Even if he was the only financial expert on earth, I'd still avoid his crap like the plague. He's practically corrupted and demonized capitalism with the way he profiteered off of racism.
If he's not willing to discuss challenging subjects like this now, the less good it'll do him overall. If he really wants the MSM's attention, he's got to be prepared and willing to answer challenging subjects. This sure wasn't setting a good example on his part.
Update: see also this article that talks about a newsletter he wrote predicting a "race war".
