The implication here is absurd, but predictable. That is, the notion that 6,000,000 Jews killed in the Holocaust, as well as the millions of members of other groups the Nazis attempted to exterminate, is an atrocity equal to a cartoon about Muhammad, or jokes about Islam in general.
Frankly, I (Marisol) find this cartoon offensive. And yet, I feel no urge to call for someone's head, burn an effigy in the street (or even a Wal-Mart Spongebob piñata, on account of the short notice), or call for the closure or legal censure of Ahlul Bayt News Agency, at whose site I found this cartoon posted under "Futurity [sic] of Insulting Islam."
Indeed, the more they prattle on, the more we know what fools they are. That's one of the many benefits of free speech.
