None of us get everything right 100% of the time, but to keep saying something doesnt work when the evidence against you is overwhelming is total insanity. I think it also hurts some because they had such great faith in their government, and the government appointed health officials. Now they can see they were being lied to for months and months, and they dont like to be wrong. These same people will continue to deny the efficacy of ivermectin until they day they die. To admit it works would be to admit their government let many tens of thousands of their fellow countrymen die. Which is exactly what happened.
