This is a new low, even for Bush haters. It represents a depth of character pathology that is quite shocking. I will go so far as to say that it is equivalent to the Islamofascist internet sites proudly showing off their beheading videos.
Please watch the video that Michelle links to. I have written about this before here.
This sadistic and insensitive display that I'm sure many consider "witty" demonstrate a hardcore lack of compassion and humanity; a vast emptiness in the souls of those on the Left.
Just make an attempt to be "witty" in this way toward any of them and the moral outrage will be remorseless.
Sorry, this is not funny; and furthermore it reveals far more about their own psychopathology than they probably ever intended.
