To me it's because there still isn't a level playing field. Take miss black America. Do you know how hard it is to be black in those pageants? Black women rarely make the top 20. The whole contest is sorta rigged against you as you're being judged on western beauty standards opposite of features you actually have. So it makes sense to want to even things by separating. I mean a 8 year old wouldn't compete with a 20 year old.
