How come one contest is not equal to the other?

First, i love people with all skin colors. it makes no difference to me. But, you have to ask yourself, if there is a Miss Black America Beauty Contest, then where is the Miss White America Beauty Contest? I believe in being an equal person and there is nothing equal about this. And, have you ever noticed a white contestant in the Miss Black America Beauty Contest? Please understand that this is not a racial question, it’s a need to understand question. Question: Why are there black contestants in the Miss America Contest and no white contestants in the Miss Black America Contest?
