I don't think "sincere" is the best word to use here.

You're contrasting "interpret him literally" with "assume he's not sincere", but I don't see a connection. It's entirely possible that he's completely sincere in his attempt to communicate certain information through a satirical article. That is, he may be honest in his communication attempt but speaking in a way where interpreting him in too straightforward of a way would lead to misinterpretation.

This is I believe what he's doing. See here for another post of mine, building on the points I made in my previous reply to you. It seems clear to me that he's writing a satirical polemic against a societal trend that he believes exists where women are not expected to bear personal responsibility for certain actions (such as voluntarily increasing their time preference through alcohol consumption).

For reference, did you read his article in full?
