Cuturally speaking is my way of thinking bad?

I always knew that because I was black I would never be considered as attractive as other people. My grandparents grew up during the civil rights movement. They told me the world wouldn't be nice to someone black. Especially if your brown skinned or dark skinned. Some people might think I'm being a self hater or I'm a downer. But it's true, look at the media I can count on one hand all the dark skinned models. Jessica White,Lance Gross,Naomi Campbell, Tyson Bedford. I don't know it's kinda discouraging..What's your thoughts? I feel like I'm just being realistic. Maybe I do need to change my way of thinking.
