Such men are defined as those whose wives don’t work outside the home. From Jezebel:
No matter how well-meaning they are, no matter how much they love their moms, no matter how much they think they believe in gender equality, men who opt to live in antiquated gender paradigms are part of what the researchers call “a pocket of resistance to the revolution”:
We found that employed husbands in traditional marriages, compared to those in modern marriages, tend to (a) view the presence of women in the workplace unfavorably, (b) perceive that organizations with higher numbers of female employees are operating less smoothly, (c) find organizations with female leaders as relatively unattractive, and (d) deny, more frequently, qualified female employees opportunities for promotion.
They presented male employers with identical job applicants—same experience, same qualifications, same resume—except one was named Dave and the other Diane. Then men in traditional marriages rated “Diane” significantly lower than Dave. Because, you know, vagina.
