Guys, don’t get sidetracked. Notice how @doomsday, @truthishidden, and the other anti-vaxxers have backed off of each claim as they are disproved and moved on to something else. First it was “CDC lies”, when that was shown to be false they moved on to “you guys are liars”, when asked for clarification it became “Google the phrase 24 vaccine autism studies” that was shown to be a product of an uneducated mind attempting to read scientific literature so they moved on to Googling “157 vaccine autism studies” (the more the merrier, I guess?), I showed them how that was similarly nonsense, so they followed up with more name calling until settling in on VAERS and other evidence-scant lawyer stuff from the early 00’s about vaccination.
Hold them to their words. Let them prove their original allegations and respond to everyone who disproved what they were saying, before allowing them to move the goalposts yet again.
