I guess they feared that in the minds of many, driven by folks like Michael Moore (another Althouse post at link) and his latest agitprop Кино, that in the minds of fellow progressives the following equation applies
SUITS=EVIL (or at the very least, Republican)
So, they encouraged the doctors in the photo to play dress up.
This brings me to one huge pet peeve of mine. The purpose of having special garb that hospital staff wear, is to minimize the possibility of cross contamination, and the original intent was that garb stayed in the hospital. The point of the lab coat is that it stays in the lab so that if some stray virus has found its way on it, the doctor in that lab coat doesn't then bring that virus with them when he or she runs off to their favorite restaurant while they grab a bite to eat. I live surrounded by hospitals and labs, and any time I'm out during lunch break hours I see a sea of scrubs and lab coats on the street and in various eating establishments. I know many hospitals have cut out laundry service, and don't issue these clothes like they used to, but that doesn't mean staff should wear these clothes out and about in public. Rather than telling people how to sneeze into the crook of their arms, maybe they should remind health professionals that they are a primary channel by which new bugs spread.
