NEW YORK — Fox News Channel anchor Megyn Kelly says she’s offended by a male colleague’s suggestion that children of working mothers don’t do as well as those of stay-at-home moms.

A study released this week showing that women are now the primary breadwinners in households with children ignited a sharp debate with two of Fox’s most prominent women taking on male colleagues. In an electric segment on Kelly’s show Friday, she criticized Fox contributor Erick Erickson for saying that in nature males are dominant.

She said to Erickson, “What makes you dominant and me submissive and who died and made you scientist-in-chief?”

Earlier, Fox’s Greta Van Susteren wondered: “Have these men lost their minds?”

The study was done by the Washington, D.C.-based Pew Research Center.
