Monica Lewinsky and Rebecca Loos both conducted affairs with married men. They weren't just 'condemned' by men. They were 'condemned' by everyone, including women. She categorizes their condemnation as 'slut shaming', but in reality they were both homewreckers.

What is it about slut-shaming that makes it an international bloodsport, even today? Is it a misogynistic throwback to the higher demands placed on female virtue? A double standard hardwired into the system? Certainly, any men involved seem generally judged less harshly. It’s usually women who carry the stigma, like branding on cattle. Feminists lashed out at Lewinsky, furious at the undermining of the Clinton presidency. Loos was taunted by Sharon Osbourne on a celebrity version of The X Factor (“Try doing tomorrow’s performance with your knickers on…”). Then again, in different ways, to varying degrees, slut-shaming has long been an unofficial branch of the entertainment industry.

She was taunted because Loos is only famous for being a homewrecker. Similarly, Lewinsky is only famous for being a homewrecker. Of course, that doesn't excuse the men in question, but it takes two to party.
