There's truth to your point, but what is it's importance as respects Michelle Obama and the reverence this author and blueflame seem to exhibit for her and her situation?
That some people with no tangible contribution to civilization are better remembered than others who have clearly advanced it progression isn't evidence of anything I can find worthwhile and in no way creates a contribution where none existed.
There is a historic sigifigance to a descendent of slaves living in the White House as one of its primary residents, but that signifigance in no way reflects (positively or negatively) on Michelle Obama and her husband.
Nevertheless, it seems pretty clear that many would argue otherwise.
If there is a positive reflection from the event, and there should be, it falls on America and its people in 2008.
Having said this, it isn't required that Mr and Mrs Obama actually live in the White House in order for America to note and take pride in its progress.
The fact that Obama has won his party's nomination and stand poised to win the election has already taken America past an important milestone.
If Obama loses in November and his wife doesn't get to live in the White House, it will not be a setback in the progress of American society.
Unfortunately too many people would have us think otherwise.
The charges of racism are already primed for the possibility that Obama loses.
The great irony is that if racism does play a role in this election, it will be the racism of liberals.
