Where's the outrage?

By now, a few of you have seen the image I posted here of someone's Twitter avitar that depicted President Obama, presumably dead, with a noose around his neck. By the number of followers to this Twitter account, one can assume there have been quite a few people that have seen this disgusting image. What I don't understand is, where's the outrage?

We've seen depictions of our president as a chimpanzee, and the Lord of Death. We've seen more than one drawing of him being lynched. When are his supporters, or even the general public going to say, "enough is enough?"

God knows those on the right would be pissed off if a picture with the likeness Jan Brewer being gang raped by a bunch of Mexicans turned up. What if there was a depiction of Sarah Palin being sodomized? I'm sure there may some of that floating around the internet, but nothing that anybody with any credibility, or someone looking for cred, would have as a Twitter avitar.

So I ask you, when are we going to hold these people accountable for their abuse of free speech? Or will it take us dropping to their level just to prove a point?
