A reasonable, responsible government that actually cared about people's lives would not be screaming "HORSE DEWORMER, HORSE DEWORMER!"
A reasonable, responsible government would be saying exactly this:
"Even though ivermectin has not been approved by the FDA to treat covid-19, there is still some evidence to suggest it can help reduce the severity and duration of illness. If you attempt to use Ivermectin formulated for large farm animals, make sure to reduce the dosage accordingly to adjust for human body weight so you do do not overdose on medication."
But no, they started screaming, "HORSE DEWORMER!!!"
I hate these people.
And also, if the substance WERE extremely dangerous, you can bet your ass they'd be in a real big hurry to classify it. The squeaky wheel gets the grease. If it's not poisoning anyone, they won't bother to classify it because there's no need.
