I heard that the darker you are the sweeter and prettier and smarter you are? is that true?

the lighter you are just says you have more (other) DNA in you,the darker the more pure your AFRICAN DNA,since we were forced over here and our women d over and over our blood line was diluted and mixed with that which is not our own so chances are you are of mixed ancestry and that is why you are light,doesn't mean that you are not sweet it's just a saying to make the dark skinned women feel good
