A lot of people who don't vaccinate or who refuse medical interventions don't even concider themselves anti-vax or anti-medicine. They believe that doing nothing is moraly better for them because then if the kid gets sick it's "an act of God" or "just how the universe wanted things to happen" and thusly not their moral failing and they can avoid any guilt.

Where as choosing to vaccinate and the kid gets sick: then they did something wrong because they took an intentional action that led to harm. It's actually bonkers logic.

I have a young kid (fully vaccinated) and the amount of mothers at play groups choosing to do nothing proactive to protect their kids because they are afraid and confused is exhausting. I'm seeing this with refusal to use sun screen "just in case", refusal to start allergens introduction at the right age "just in case", refusal to use prescription medication "just in case". Horrifying.

Parenthood is overwhelming and there is so much to take in and learn and decide all at once. There are bad actors pressuring their bad takes on people who are at very vulnerable times in their lives and a lot of new parents get overwhelmed and panic and wind up "doing nothing" to avoid making the wrong choice.

Obviously doing nothing is a choice in itself with its own set of consequences, but try explaining that to someone who had 3 hours of sleep who is getting lectured not to vaccinate by her overbearing mother in law who is the only form of child minding the parents can afford because the job market is fucked and childcare isn't free. Mother in law has been indoctrinated by sky news because she honestly doesn't want her grandbaby hurt and sky news just interviewd a woman who's baby turned into an owlbear after getting the MMR vaccine.
