Don't know if I can be bothered. Might log on and dump links to the Vaccine ingredients podcast on Skeptoid, but beyond that, I really don't have the patience to debate these people. Trying to talk to conspiracy theorists is like training a cat to fetch sticks; they have their minds made up frmo the get-go and will just sit back and bombard you with smugness, insults and links to dubious sources until one of you gives up.
ETA 1: My favourite header so far: "Vaccines affect the immune system". No ****, Sherlock, what did you think they were for?
ETA 2: Ugh, that's enough for me. If I read any further, my blood will boil.
