It's no secret that Pinterest is the devil. It's a time-sucking, hetero-normative, copyright-infringing vanity site that appears to exist to make women feel bad about their appearances and subpar crafting skills.
It also skews heavily toward women. That, apparently, was unacceptable to men -- straight men who hate paying attention to the people they want to fuck, specifically. So now there's Manteresting, a Pinterest for dudes, and it's a helpful reminder that feminism still matters. Because wow, do these guys ever hate women.
