Remember that viral loads for this have compromised the immune system of young, healthy healthcare workers all over the world. They are dying everywhere. The question - what would the viral load be if everyone took this advice and the average young family came into contact with hundreds of infected people during activities like this?
Let's say that only a handful of children die because of activities like this around America. Sounds like something that is statistically so low a probability that one would be willing to take that chance - unless your child is the statistical anomaly.
There is far more that we do not know about this than which we do. I would not want to be the one going on the internet and telling other people that it is safe. We don't know. And, if we are wrong and we influenced someone into doing something that they might not have otherwise done, we are complicit.
