Joanne Bamberger at Politics Daily‘s “Woman UP” is really bothered by a cartoon of a fat Michelle Obama posted at Andrew Breitbart‘s BigGovernment, which she calls a “playground mockery.”

Bamberger, a new writer for the site, wonders if the cartoon’s artists, James Hudnall and Batton Lash, are attacking FLOTUS’ initiatives or “dismissing her efforts by wrongly suggesting she’s a Fatty McFatterson.” If that’s the case, it’s childish: “Portraying the first lady as an obese glutton is like resorting to a classic elementary school taunt: ‘You’re ugly and your mother dresses you funny.’” (Bamberger obviously hasn’t been in elementary school for some time. Kids are far more likely to make sex jokes about each other’s mothers than to say that their mother dresses them funny.)

Bamberger closes with a lesson from an important, timeless movie which we can all learn a little something from, “Mean Girls:”

“‘Mean Girls’ isn’t a political movie, but it has some advice that today’s politicians might want to keep in mind — “Calling somebody else fat won’t make you any skinnier.” And, I’d add, it will never advance your agenda, especially when the person you’re talking about isn’t fat at all.”
