Are you afraid you might not be able to defend your position against them?
Well, I clearly won't be able to defend my position. There's a lot of scientific studies about the near-impossibility of convincing conspiracy theorists (or anyone with strongly held counter-factual beliefs) Pointing out conflicting evidence makes them double down. Beyond using logical fallacies to justify their position, the number of biases humans can employ to avoid thinking is huge.
Look up SV40 polio vaccine from years ago
A mass biological product was contaminated in ways totally independent of its use as a vaccine. I didn't hear anyone calling for banning all guacamole cause some avacados were found with E Coli.
I'm happy to admit that there are occasional problems. But that's not what any anti-vaxxer has claimed. The vaccines of today are massively tested, and the specific issue you brought up was the distribution of an unknown pathogen that evaded all tests. Also, it was still a net positive to wipe out polio.
getting sick of these anti-science whackos like you that think scientific discussion should only be what YOU approve
I'm not saying that. No one is saying that. If experts want to debate the merits of specific vaccines, that's great (assuming there are reasonable people on both sides of the issue). But that's not how anti-vaxxers are spreading disease through my community. They use conspiracy theories about pharama companies profit motives and disingenuous anecdote picking.
In some cases, ala Jenny McCarthy, her son personally almost/did have his life destroyed because her crazy anti-vax faux-autism was a disease that is sometimes treatable if caught early. Instead she doubled down, then said she cured autism as he's somewhat recovered.
convincing people vaccines are good SHOULD be easy
You're right, it should be. And one step for that to happen is for the medical community to treat anti-vaxxers the way they treat phrenologists
