well, speaking of black quarteback, well my first year coming to us ,then i visited some friends in north calfornia, pretty much fresh and had some idea about america but not the menatlity of people .one nite invted in real nice gentleman,his wife,son,his brother .in dinner table we argued ,friendly .then we talked about here,there and things came to issue of racism ,stuff like that .they were living already a good 20 years before .as my own the way of thinking which i think all the human have same ability but different talant ,that good friend came up with this ..you can't see even black quarter back in all the football team, i was really shocked ,my knowledge of american football was much much less .so i started asking the questions in that regard ,that friend finally told me ..it is not about racism or trust it is about the leadership .so that me thinking it is because they don't want the leading position or the others don't believe they can't or they don't want that .
when i came back from that trip ,he was right though ,they have all the key positions except the quarterback position.
long after invetion of creation of internet ,i brought it to debate here ,like so many things which it is question for me ,not because i don't know the answer but why even such of way of thinking exist .however after while we see the differences ,not only that they are actually good quaretback if they want to be .
or president if they want to be .so why we see the things black and white .maybe it is just way it is. it human can correct them selve .
