It is that bad. The motivations are different but the end result is the same. Honestly, a bunch of soccer moms endangering immune-compromised students in suburban America is nothing compared to campaigns by developing or crowded regions like Africa and India, often driven by local/tribal leaders on the back of religious doctrine or anti-western sentiment.

In some cases, they probably are trying to "kill children" or at least don't care if it happens, because they're simply using it as a tool to consolidate power and create a boogieman. I think most often though it's pure ignorance and stupidity. Maybe it's religion instead of naturalism but it's ultimately that same distrust of science. They genuinely think they're doing the right thing which honestly makes it scarier. There is some pure evil and malice for sure but honestly most of the decisions that have created human disasters throughout history were usually made by someone who thought they were right on some level or another.
