Anti vaccination hysteria threatens the health and possibly lives of their children and the general population as well. And yet they hold firm to debunked theories while refusing to accept tried and true science.
Happens all too often in this as well as other aspects of our lives.
Real science is denied and fake science is held as truth. Same with climate change.
It's the dumbing down of Americans syndrome. When did that happen and why? Just boggles the mind!!
