If it is not too late to chime in, yes the site is supposed to be dead serious. The site creator is one Andy Schlafly, who is a home school teacher who seems to genuinely believe that girls are naturally less intelligent than boys and thus gives them easier tests and more time to take them in. His mother is Phyllis Schlafly who, among other things, does not believe that there is such thing as marital rape (“By getting married, the woman has consented to sex, and I don’t think you can call it rape.”)
And yes, there are a ton of people who write parody articles on there. Thanks to Poe’s Law though, it’s kind of hard to figure out which is which. As a result, Andy has gotten extremely paranoid about “vandalism” and bans people at the first sign of disagreeing with him.
I’m not 100% certain on this, but I also heard that the site is run by Andy and a group of homeschooled teenagers called “The Panel” (which would explain what Lama said about the simplistic writing). Oh, and the site seems to be working on rewriting the Bible to edit out liberal leanings. Hand-to-God, not making that one up at all.
