Being tan doesn't give you cancer, excessive tanning can promote cancer. There's a difference. If you tan easily, it's no different than a fair skinned person being out in the sun for the same length of time. If anything, you're better off than a fair skinned person who gets a sunburn after being outside in 30 degree temperatures for a half hour. In fact, a little sun is good for you. Today's generation is having health problems due to sun paranoia. You need some sunlight for the Vitamin D and it's just not the same as getting it from milk or vitamin supplements. In other words, don't fear the colour. Just remember not everyone tans equally, otherwise every dark skinned person is doomed to skin cancer. The warnings are for those who can't tan yet go to tanning booths constantly and come out looking like a cooked lobster. Not for people who have more melanin.
Your fourth point is one that can be corrected by saying "no, fake bimbos are orange and look like they have footballs stuffed in their shirt". The tan/blonde look can look good if it's done right/natural.
