Please explain this to me I’m still lost on this thing.
You take 20 people and put them in a room for 5 hours - all masked.
Halfway thru this time together, they all take of their masks for 30 minutes.
Are they protected from transmission?
This discussion reminds me of memes like the following that have circulated around:
It's supposed to be this "gotcha" moment indicating the rules are silly, but are they?
Short of a full lockdown, we were never going to be completely isolated from other people.
If social distancing is possible, like in a line-up, do it. If it's not possible, like on a plane, decide if the situation is worth the personal risk.
If I were to fly during the pandemic I'd still avoid close contact with people outside of the crowded plane. Is it 100% safe? Of course not, but it's safer than being in close quarters with people on the plane AND multiple people in all of the various lines prior to boarding.
Whether the school policy is the right one is up for debate, as is whether or not people should be flying at all, or visiting theme parks at all, etc. However, when we talk about these situations that carry some degree of risk, it's still smart to find ways to reduce that risk.
Compromise has always been the name of the game. WDW opened with masking and capacity limits, allowing people to work and enjoy some leisure while still taking steps to reduce to risk. That's why many people expressed concern when WDW made masks optional indoors. Few people were saying to shut it down completely, but were saying that given the situation the amount of risk mitigation is insufficient.
