it feels like you're setting up a false eqivalancy; I didn't read anything here about people putting on sunscreen religiously who never go outside, nor you'll die without sunscreen. It seemed to be clearly seperated themes:

1. people are mad about the original topic - false claims of effacicy, when sun exposure can be very damaging and cause cancer.

2. alternatives to these sunscreens, including mechanical like hats and clothing; questions about mineral alternatives

3. wild theories like this one, where a base tan or early season burn somehow protects you. These are wrong and should be called out.

How do you know? I would default to the natural approach of yes sure keep in the shade but also man people evolved / were created spending a lot of time outdoors.
