I may not recognize some of the things that blacks go through.   Are you also denying some of the things that you go through as a white man?   Things like being called racist and privileged just because of the color of your skin?  Even though you may have been demeaned and physically abused just as much as any black man?  And do not say that whites do not get demeaned.   Just have a slight difference from normally.  You might be white in a majority black district.   You might be shorter than normal.   
Plus, discrimination in and of itself is not bad.  There is good discrimination too.  How else do we decide who to be friends with, who to hire, where to live, where to work.  This all involves discrimination of one sort or another.  Almost everything we do involves some sort of discrimination.
