It was ridiculous of Mike to question Dr. Garrett Smith's authority on the subject.Well Mike Fave is mocking Garrett in his twitter biography: "PUFA Maxxi | Estrogen Evangelist | Serotonin for Happiness | Anti-Vitamin A Crusader | DHA Snorter | The Real Nutrition Detective"
Also the preview is cropped so you can't see it but in the beginning of that "tweet", he addressed Garrett thusly: "Thanks for enlightening us "Detective"". That's why Garrett responded by putting "Mike Fave" in quotation marks.
