I prefer this account of who Michelle/Michael really is:
“Michelle Obama, First Lady of the United States, was born Michael LaVaughn Robinson in Chicago, Illinois on January 17th, 1964. He was the second son born to Fraser Robinson III, a well known cocaine dealer and union thug for Crime Lord/Mayor Richard J. Daley, and Marian Shields Robinson, a transient street prostitute who was diagnosed with the HIV virus in 1998.
