parents who don't vaccinate their children shouldn't be allowed to have kids
"But my son might get autism!!"
Although I think parents should have a choice, but only if it's a reason that can be backed-up.
example "X vaccine is
scientifically proven to give Z".
There is no scientific proof that vaccines cause autism.
It can be scary for some people not knowing what's actually being injected, not saying it is something bad, just saying the thought can put others off.
