Dr. Paul Offit Says RFK Jr Is a Mean Person & Vaccines are 'Undebatable'

"You can debate the undebatable depending on the debaters. For example there was a debate between Ken Ham...and Bill Nye the Science Guy...Bill Nye went through a series of facts showing why Noah's Ark couldn't have happened...and goes through a lot of that evidence but it's in a respectful way. I just don't see RFK Jr as that person. He's constantly putting other people down...it's mean spirited."
