Vouched for this because I don't see any reason why this was flagged. Sorry if I overlooked something.
I guess some people are uncomfortable with the issues raised in the article. Alternative explanation: some users are trigger-happy and flag an article based on the headline before they have a chance to read it. ~Its un-flagged by now~, and I vouched too BTW... Its a good article and a balanced discussion about feminism would be very nice to have here...
Saying people's preferences are "Problematic" is a way to pressure them into sex: "You're a horrible person if you don't have sex with me!"
