Maybe because, in the long run, hair colour preference really doesn't matter. I've always been attracted to redheaded girls. I'm now in my first relationship ever and my girl doesn't have red hair, but I'm cool with that, she has so much more to offer than surface preferences eg. godly, fun-loving character, an inquisitive mind, a beautiful soul and the skills and talents God has given her. And that's just the beginning. She's not a red head, but I love her!
