Astrology To the Rescue of the National Health Service?

From the Guardian: UK Conservative MP David Tredinnick says astrology could help National Health Service physicians out by assisting in diagnosis but says he knows that there would be enormous pushback from using it. He accuses those who refuse to see the value in astrology of being "racially prejudiced." I'm not sure exactly how being skeptical of astrological claims makes one "racially prejudiced." Is there a correlation between acceptance of astrological claims and membership in certain ethnic groups that I have somehow overlooked? I would be really interested in that data.
