This is such crap. This nation has not assured by any measure, much less to the greatest extent possible, that equality of opportunity for all Americans exists for black people. In fact quite the opposite is true and it is a matter of historical record. 
White America may not be able to atone for slavery, they have can atone for segregation and yet still have not done so, so please spare me, but more importantly those who are DAILY victimized by racism, the insulting homily, Mr. Loewy. White people wouldn't last a day walking in black people's shoes. 
"We must move forward"? Isn't that another way of saying we're still ignoring racism like we always have been?
