Even if it were linked to autism, at least there are high-functioning autistic people. Anti-Vaxxerism seems to be a much greater and more crippling form of mental retardation than autism.
There will never be 100% vaccination, and nobody claims there ever will be. There are people who are actually unable to receive the vaccines for real, medical reasons. And, by the way, those are the people we actually care about who you anti-vaxxers are putting at risk, real, functioning human beings. If it was only anti-vaxxers putting themselves at risk, I would be fine just viewing measles as Hashem’s way of cleaning up the gene pool.
