“That isn’t the claim. The claim is that an additive to the vaccine is causing miscarriages. (By the way, I will need more information before I decide that this is actually being done.)”
I’m with you - I’m skeptical until I see better evidence. Otherwise it just sounds like more of the usual conspiracy nut stuff, like that which posits that the CIA is responsible for creating and spreading AIDS and Ebola (to what imagined benefit, I don’t know). OTOH, this one is not entirely out of the realm of possibility.
