Love the final explanation for how ivermectin can be incidentally good for COVID-19 patients, even if it does nothing to COVID-19 directly.
In fact, as the author cites from another researcher, the trials are a strong piece of evidence for "add[ing] ivermectin to mass drug administration programs." In other words, global medical welfare, where we just give everyone a bunch of a cheap and effective medications to counteract the most prolific diseases. In addition to reducing mortality from diseases targeted by the medication, it will probably reduce incidental mortality when people contract multiple conditions at once. I.e. getting ivermectin for a detected COVID-19 infection has a 10% chance of helping you, because you have a 10% chance of having an undetected worm infection that will kill you if your immune system is suppressed by drugs that are used to prevent COVID-19 from killing you.
I do think the ending political metaphor doesn't quite fit, however. I see more parallels with workplace politics than an alien invasion, for why our societies have become so divided on relatively meaningless issues. Uniting disparate factions to work towards a common goal is an uphill battle that sees more failure than success, most often in our workplaces. To me, the ivermectin drama was just another example of an emergent situation that wasn't optimally handled by a collection of random individuals, who despite the best intentions, were unable to unite a group. Doesn't make them bad people, or mean they have the wrong approach. Just means they weren't ready to tackle such a difficult challenge. Positive outcomes take dedicated effort, they don't come automatically because we assume the status quo is good enough to us immune to random chance.
