Count me in the “sunlight is not instant death” camp, even if I am vampire-white.
It’s a little more complicated that “always use sunblock”. People really do need some sunlight on their skin for the vitamin D. Very pale folks don’t need much, but they do need it.
Tanning is the skin’s reaction to damage from solar radiation. Therefore, if your exposure is minimal enough (regardless of time of day) that your skin color is not changed then the damage is probably minimal as well.
Sunblock does not prevent all damage, but it does encourage people to stay out in the sun longer, at least in some cases. It is possible to cause more damage to your skin by slathering on the block and staying out in the sunlight 8-10 hours than by doing without the block and getting much shorter exposures.
Family and personal history is also important. Folks with family histories of skin cancer, or with a personal history of severe burns in childhood, should err on the side of more sunblock, shade, hats, and long sleeves. But even they need some direct sunlight.
I’d say the only people who truly have an argument for “never” in regards to sun exposure are albinos and those who have xeroderma pigmentosum. In which cases vitamin D supplements may be called for.
