Why do so many people think that Black Folks demand affirmative action?

I'm a Southern White man, and I come from the Black Capital of the World, the Mississippi Delta. Black Families and White Families have been living together here for almost 450 years, long before America even existed. Why is it every time I travel up North, people have the misconception that Black Americans demand Affirmative Action? No Black Person I have met ever said to give him or her a job because of his race and exclude other races. Although it is crucial that the Poor Black's are helped because we must remeber that unlike my great grand parents who could save money and property and p it down to future generations, Black's were not even allowed to open Bank Accounts.
