Why would you want ‘especially blacks’ to respond, when your question is about white people’s behavior? I am a white Irish male, and I have two colors: white and pink. The pink one hurts like hell. We get a bit obsessed with sunblock because recent media reports have highlighted the link between sunburns and cancer, and though we would like a tan, we would prefer not to have to die to get one. Most of us have at least one friend or family member that have gotten a skin tumor (three cheers for global warming). One of my friends from high school recently died from skin cancer. So we’re deadly serious about the sunblock.
