Why do some black people think they are not supposed to wear sunscreen

Haha I wear sun screen and I make sure it's grey on my skin. I like to see where I've applied it. When I went on holiday with my family they said I think I'm like white people! Sad thing was I was all golden and brown whilst they were black and sunburnt. I do the whole aftersun too. My skin was so lush! I already have enough factors going against my skin with acne. I don't need to make it worse with damn melanoma, melasma and whatever else.
Body= temple and all that... lol
