Nine men and women of medicine who once led the Centers for Disease Control and Prevention under both Republican and Democratic administrations have written an open letter you might want to read. If you don't have the time, I'll summarize it for you: Robert F. Kennedy Jr. is a fucking idiot who doesn't know the first thing about medicines, diseases, vaccines or health and his uninformed decisions are going to get a lot of people killed.
I do not understand why Kennedy has any support from anyone. If nine people with a long history in the field of fire prevention told you that your home was in imminent danger of a major blaze, would you instead believe some guy who didn't understand what a hydrant was?
