Nice theory.  But when the 'imperfections' of other people--specifically those who control our social, political, economic, legal and educational institutions--are expressed and implemented as white supremacy, they place massive barriers in the paths of folks who ain't white trying to raise their children, work, get ahead and all those other nice platitudes you mention.  Barriers you've clearly never had to surmount, so you can complacently ask "how hard can such barriers be?  I haven't noticed any".  Of course you haven't.  No one has turned down your employment, loan, scholarship or rental applications because your face is the "wrong color".  You've never been hemmed in by such appalling lack of options you'll risk crime to feed your children.  And before you bring up the pitiful and wholly inadequate remedy of "affirmative action", recall that back in "the good old days" affirmative action was the EXCLUSIVE property of white Americans.  I'm old enough to remember that.  Are you?
