In Ron Paul's newsletter, a ghost writer (recently
identified) injected his own venom into less than 1% of them at a time Dr. Paul was between Congressional seats and hard at work at his medical practice of delivering babies (to which no one ever claimed he did anything but an exceptional job at, mind you).
Since this is all the Power's That Be have on Dr. Paul, they took this and exploded it, trying to imply Dr. Paul is everything this ONE ghost writer injected into the newsletters, which was very unfortunate and Dr. Paul has disavowed these remarks repeatedly and took moral responsibility for it happening under his name.
Ron Paul supports the rights of the individual and is a champion of civil and economic liberties, both that go
against racism. Dr. Paul is against the failed drug war, which harms minorities the most. Dr. Paul changed his stance to be against the death penalty (one of the few stances he's ever changed) because he saw how it was biased against minorities.
Here's a good video (with a sarcastic title!) that shows Dr. Paul himself speak out against racism and defacto racist polices:

Here's a video that shows what Dr. Paul did for an interracial couple who were being discriminated against at the hospital:

Here's a video of a collection of clips of African Americans and their support for Dr. Paul:

Ron Paul is also against U.S. foreign intervention, which has historically been military action against poorer minority countries. Dr. Paul believes in diplomacy, trade, and good will instead of force.
