The kids weren't in danger, that appears to be changing very quickly with the new variant. Let's not be like George W. Bush standing on the aircraft carrier saying "mission accomplished", when we're still in the middle of this thing.
Death rate for kids with new variant please?

That said, my kids are wearing made in the USA masks.
Until there is data that shows conclusively that Delta affects kids more than previous variants, you should not parrot lines like "that appears to be changing quickly". Substantiate your claim with data or at least say it's anecdotal. Alternatively, if you have data, please share it.
We can send the kids back to school with no vaccines, no masks, no precautions, and say "We don't have any data that this thing is dangerous for children". The obvious problem there is that we don't have a ton of data in general with this variant. So, if we're wrong about the danger, we risk harming a lot of children while we dutifully wait for the data to roll in.
This is the same reason that most women (and many men for that matter) will cross the street late at night if they are on an empty street and see a large man approaching them. They have zero evidence suggesting that the person is a threat, but the cost of being wrong in such cases is very high. So, having limited data, they tend to take a very cautious and conservative approach and cross the street. In our case, just change, "Cross the street" to "Wear a mask".
This comparison is far from perfect, but you get the idea.
In other words, whoever makes a claim that things have changed better provide a reason why it is reasonable to think things have changed. Typically that comes in data.
No arguing on Hacker News is going to change the policy response anyway.
