Besides the way-too-obvious and not particularly funny references to "double- wides" and "riding lawn mowers" (hyuck! yuck! yuck!) this parody is about Hitchens AS-A-LEFTIST and is making fun of him for being a leftist. Very little is specific or shows knowledge of Hitchens work (I will grant a bit of credit for linking his pro-war stance with popular pro-war fervor but even that was not very sharp or clear).
The only thing funny about that is they don't appear to know much about Hitchens. Now lazy satirists getting street cred while serving ye olde tropes about irrelevant alleged leftists. That's funny.
I think getting the details right is what satire is all about. The closer you can come to the source material and still manage to turn it on its head the better.
