How is that racist?

Via Politico:

Barack and Michelle Obama are sharing their own personal experiences with racial prejudice, saying they’ve been mistaken for valet drivers and Target employees—the latter even occurring during their time at the White House.

“The only person who came up to me in the [Target] store was a woman who asked me to help her take something off a shelf. Because she didn’t see me as the first lady, she saw me as someone who could help her,” Michelle Obama told People magazine, recalling a trip she made to Target, according to excerpts released Wednesday.
