No, What Kathy Griffin Did Wasn't The Same As What Snoop Dogg Did

While I think most people generally agree that what Kathy Griffin did was off-putting and inappropriate, few seem to have an idea as to why- other than pointing to the gory and violent nature of the photo. For me the point of distinction again is satire. I defended Snoop Dogg's actions because they clearly constituted satire, while this seemed to be some sort of mix of desperation and genuine hatred devoid of any broader significance. Maybe I'm missing something here, but this seems to be primarily about shock value- not about art or satire.
