I am at a loss to understand what constructive purpose first lady Michelle Obama (and President Obama, Eric Holder, Jesse Jackson, Al Sharpton and others) hopes to achieve by constantly talking about the race issue.

Last Friday, Michelle Obama chose to celebrate the 60th anniversary of the Brown v. Board of Education ruling — in which the U.S. Supreme Court declared state laws establishing separate public schools for black and white students to be unconstitutional — by reminding graduating high-school seniors in Topeka, Kan., that racism is still alive and well in America today.
