It's long (10,000 words) but I wanted to rebut their letter as much as possible.
I have posted it to my blog here on the forums.
I've also sent an abbreviated copy to my Senators and will be sending out as much of the complete letter to as many people in D.C. that I can.
I don't expect one letter to change anyone's mind, but many letters can. Please write to your representatives and to the FDA acting chairman. It doesn't have to be long, just polite and factual.
