Why?

OK so for quite some time I have been thinking about this, but was not sure whether to post it. So here I go...I have seen many different places that only allow blacks in it. You got the Black Chamber of Commerce, You got the black beauty pageant. You got Martin Luther King Day, The list goes on & on. These places don't allow Whites or any other race to be in any of these groups. I ask is this a form of racism? We have a Chamber of commerce that anyone is allowed to be in, we have a beauty contest that anyone can be in. We have all that everyone else has, EXCEPT for a whites only group. Now I am in no way prejudice. I am just asking why can't this be an equal country? Why are we still separating the colors? It was wrong for white people to take in slaves & treat blacks or any other race wrong right? Well why is it right for the other races to have their own clubs? Really I mean look into this. Prejudice or not this is wrong!
