Michelle Obama has behaved, spoken and dressed poorly. She is the First Lady and thus has an obligation not to bring shame or ridicule to that office. She has done that, not just in this country but when visiting other countries and other dignitaries. In addition to not living up to her responsibilities and has insulted our country, its people and its flag. She has earned every criticism.

I don't criticize any woman for having a big butt.
