"A Modest Proposal" gets the same kinds of responses...
There are a few points to writing something satirical, one is to amuse individuals with a similar viewpoint or those able to see it for what it is... Frequently it's used to identify something seen as negative by blowing it out of proportion... and it's also used to identify people who simply don't "get it"
Along the same lines but not quite as subtle is the site http://www.petsorfood.com
which frequently causes similar responses (Although herpers seem to find it amusing).
