There's been a few of these key anti vaccine, covid is just a flu types get killed by covid recently in the US, a lot of folks there poking fun at them, so the FDA line is not out of line with that.
The FDA is a government body, they are completely out of line mocking people no matter how foolish their cause of death.
Ivermectin is an anti-parasitic. River blindness is a disease caused by parasites. Covid isn’t.
Yes, so imagine the outcome if a community in deepest Africa getting a hold of information that imparts the opinion that the white man is giving them stuff meant only for cows and horses or is somehow unsafe... Also, if people are buying ivermectin from animal suppliers, treating people like they're stupid usually works really well to convince them to change their behaviour, doesn't it?
Honestly, there must be some freaking adolescents in charge of the FDAs social media.
