From her Tumblr*:
Pro-vaccine advocacy is not the same as advocating for the rights of autistic people or being anti-ableism. Pro-vaccine advocacy can sometimes repeat the same pernicious, ableist myths about autistic people which are so embedded in the anti-vaccine movement.She's absolutely 100% right; where the anti-vaccine activists' rhetoric implies that it's better for one's child --- and other people's children, for that matter --- to contract potentially life-threatening, vaccine-preventable diseases than to be autistic, the pro-vaccine camp usually responds with "Nobody wants to have an autistic child, autism is a terrible tragedy and we should hurry up and find a cure, but ..."
It's a conciliatory tactic, meant to convey empathy for the clearly-distraught parents who blame vaccines for their children's disability. And that's good, as far as it goes; everyone deserves to be treated respectfully, and to have their feelings acknowledged and respected when they're debating emotionally-charged subjects.
A discourse that rests on the premise that autistic people should not exist isn't one that respects autistic people. It also implies that there are no autistic people participating in, or watching, the debate, and that's just not true. We're here, we have a personal stake in these issues; we deserve to be equal participants in the public discourse around autism.
*I can link to the post itself, but currently if I do that you're not able to read it --- other text overlaps with it. This is one of the many reasons Tumblr fails to appeal to me.
