The whole flap reminds be of a shaggy dog story. Others can put all the shag back on the dog. The punchline is, "If the foo sh*ts, wear it." Dunno why that comes to mind in the midst of this particular subject. LOL.
In my opinion, I happen to agree with the CAIR interpretation of his intent, but sadly for them, "reading between the lines" is not actionable, and Mr. Hart certainly has plausible deniability here...the ambiguity of the cartoon is the beauty of it, and the "foo" comment is exactly right on, LOL!
