You're obviously an idiot if you think a piece of cloth that doesn't seal over your respiratory passages somehows protects the wearer from anything
And so is anyone who like your post.
I think that a more rational explanation of the situation is that the White House staff and Trump family failed to follow some basic precautions related to safety in a pandemic. It's not about masks or lack thereof; that's just the most physically-obvious symptom.
It seems that the administration relied upon a test (specifically the Abbott Labs BinaxNOW PCR test) that has generally-acceptable sensitivity and specificity for
symptomatic carriers, but which is wildly unreliable for those not yet exhibiting symptoms. It's rumored to generate false negatives in about 1/3rd of the pre-symptomatic cases, so that makes it pretty much useless as a screening tool. And then they decided to
randomly screen those near the president instead of implementing 100% testing. So now you're using a test that only works ~67% of the time, multipled by the random test coverage interval. Given your background in manufacturing engineering, I'm pretty sure you can easily point out the flaws in this plan. If we were talking about, oh, maybe a supplier of snap rings, you'd be pretty pissed if their control plan looked like the President's screening protocols.
While one can argue for or against any number of disease protection countermeasures as it relates to a private citizen, the President is not a private citizen. His health is a national security concern, and it's clear that him and his administration got sloppy. They had some warnings over the past two months that there were holes in their protective measures, but I'm guessing they used those near-misses to rationalize the effectivity of their scheme. ("It got really close but never hit us directly, so we must be doing something right!") Pretty normal human logical fallacy, right?
So, no, this isn't about whether or not the President wears a mask.
