Philanthropist means something like "humanity-lover"; would they be:

* Misanthropists (humanity-hater)?

* Philnosists (disease-lover)?

Apologies for my extremely poor knowledge of Greekish (by which I mean "scientific-ish English with Greek word roots").

Well they certainly don't love humans if they are anti-vax. They are instead well funded misguided fools who will cause death.

So I'd worry less about the Greek, more just call them idiots and assistant murderers.

anti-vax aka pro-disease

This is a great term that clarifies the debate. We should all start using this.

It is why I try to use it when feasible. It does a better job of indicating "the other side's" views.

I don't think we should. Calling people names won't help change their minds.

Call them something that indicates the true problem: misinformed.

willfully ignorant?

Right? You either love vaccines or you hate humans. It's simple.

I hate humans. But I'm still pro-vax.
