That's DOCTOR Kailin to you, sir.  

HER title comes from an MD, not just a DDS.  She knows more about the effect of water additives on the human body than you'll ever learn.  Plus she knows it first-hand, from doing some of the seminal research on the topic, unlike you.  She has been employed by governments at all levels to consult on the topic as well  --  you are just employed by Pew et al to parrot the scripts they give you.

(That name I called you was just exasperated shorthand for the above, regionalized to reflect the fact that you live 3,000 miles away from the water we drink daily.)
