Care to back this up?
On his TV show, early in the Clinton administration, Limbaugh put up a picture of Socks, the White House cat, and asked, "Did you know there's a White House dog?" Then he put up a picture of Chelsea Clinton, who was 13 years old at the time and as far as I know had never done any harm to anyone.

When viewers objected, he claimed, in typical Limbaugh fashion, that the gag was an accident and that without his permission some technician had put up the picture of Chelsea - if you believe that let me sell you this bridge I own in Brooklyn!

Of course, he is not alone with his comments about Chelsea. In 1998, at a Republican Senate fund raiser John McCain said -
"Why is Chelsea Clinton so ugly? Because her father is Janet Reno."

Misogyny is contempt of women or girls. He has said things throughout the years that qualify for that description. Remember feminazi?

As for the morbidly obese - just the observation of a nurse.
