Wearing a mask helps, but still one has to question the rationale behind the mask mantra. Neil Cavuto asked a doctor the "simple" question of masks improving people safety at so-called super-spreader events. The expected answer of course was a resounding emphatic "yes". But to her credit she said that the positive safety effect of wearing masks at these super-spreader events was less than projected. Well OK, still positive.
After she answered, Neil had the foresight to ask a really good follow-up question. He noted that in other countries, implementing strict mask protocols plus distancing, that cases are rising (spiking). Well at that point the doctor went into "damage control". To paraphrase: "Well, we don't know this ...., we need to examine this ... other factors... etc." The net take-away from this is that we really don't have a handle on the efficacy of masks.
Masks are better than nothing, but those pushing a fear based mask mandate and other aggressive actions are being overbearing.
