Lena Dunham isn't one to keep her opinions to herself. When espnW's Allison Glock asked the actress and comedian about the body-shaming of female athletes, Dunham was quick to offer her own two cents.

Easily the two most famous female athletes at the current moment are Serena Williams and Ronda Rousey. For all the fame and media attention they enjoy, those two are also subjected to rampant criticism -- particularly online, where discussions inevitably turn to their physical attributes -- for better or for worse.

As physically strong females, they often have to face body-shaming for physical characteristics commonly attributed to men. Dunham thinks there's a simple explanation for why men feel the need to engage in such shaming tactics.

"With Serena Williams and Ronda Rousey, men are thinking, 'You could beat me up, that [expletive] scares me, you have achieved more than I ever will in my lifetime, so I'm going to get online and tell you that you don't look like someone I want to [expletive],'" Dunham told espnW. "That is where I believe it comes from. And it's so unenlightened. And man, it's a bummer.

"The fact is, Ronda Rousey could punch you in the face anytime she wanted, and she has completely created her own life and she's having an incredible career that most of us could only dream of."

In Dunham's view, Williams and Rousey are unnerving to certain men because their accomplishments supercede any power those men might be able to claim over the women.

"And that point of view is really, really threatening to certain people, especially when it comes in the form of a woman, because to a man, a woman not caring what you think means that all your power is gone. You can't control her anymore," Dunham said.
