To be honest, this article is hardly written completely with a straight face. It has a cheeky tone throughout. Which isn't to say it doesn't provide interesting points for the layman.
Of course, it does have a cheeky tone, though I think all of my points stand. The "interesting points for a layman" are actually a series of straw-man propaganda arguments. It does not argue in good faith and it should not be afforded the legitimacy of a thoughtful opposing position.
If something is a straw man, you're not going to discover that by looking prima facie.
Like, I could counter this article by saying "this dude thinks evolution has made humans as intelligent as it's possible for anything to be, but there's no reason to think that's so". And prima facie, my argument isn't outlandish. Nevertheless it's a total straw man.
