Black people who spend all their time indoors or covered up will get sunburned if they go outside. If that black person gradually increases their sun exposure they can (in a few weeks) reach the point where they can be outside without sunscreen and they will not get sun burned.

Note that I'm making no claims on how natural sunburn resistant affects skin cancer.

Increased melanin provides some protection against burns, but it doesn’t make you immune. There’s also the aspect of UV damage without burns, which is still harmful and is not affected by melanin levels.

that's his point. anyone can get sunburned, and almost anyone can prevent sunburn through gradual exposure. except albinos, who are especially susceptible.

melanin is also not the only factor in preventing sunburn/cancer. there are many repair pathways and genes, which are present to differing levels in various populations.

The same is true for me, a white person of northern European heritage. If I have a few weeks and time to work at building up a tan, I can get to the point where I won't burn. I did this during the pandemic when I was home all day. I would go out and lie in the sun, starting at 15 minutes, turn over, go another 15 minutes, and go back inside. Increased the time as my skin darkened. Felt nice, never burned.
