For CDC:

You know which camp I am in. So let's examine the argument being made by the other camp:

The authors of this study make one of the most cardinal errors in all of epidemiology. They ignore the principle that "correlation does not equal causation."

Apparently, the science no longer matters. You can acknowledge that a study does not allow you to determine the direction of a relationship, but then go ahead and draw such a conclusion anyway. Frankly, this is junk science, and it is just as bad as what we have attacked the tobacco industry for doing in years past.
