The NBA&the Racist Age 19 age Requirement

how is the NBA gonna be able to set a Age entering number at 19? it's Racist&Very Loaded. be it Acting,Movies,Music,Tennis,Golf,Hockey,soccor,etc... a Kid can be 18&earn a Living. if you can be sent off to war at 18 then you can Play Pro Basketball.nothing about this from the NBA makes any sense.some kid will come along&take this dumb law passed by the NBA to the Supreme Court&easily win. Maturity comes in all ages.some People are very Mature at age 18&some People are still childish at age 58.too much Politics involved&this is about control but has very little to do with Basketball. I've seen Cats go to college&come to the NBA after 4 years&still be Busts. the argument is that many Kids enter the league&Very few turn out like Kobe,Amare,Garnett,Jermaine O'Neil,T-Mac,etc..... but everything is a Gamble&lets be real:if you want to make a Living Playing Ball&don't want to go to School then why should you?I feel this passing Rule by David Stern is Racist&also Unconstitutional.
