Believe it or not, I generally try to let these things go, if for no other reason than protesting them is throwing good attention after bad provocation. But I do love Michelle Malkin's suggestion for the artist:
You want edgy? Go ahead and create "Mohammed Killa." Replace the Homicidal Jesus Christs with Homicidal Mohammeds mumbling cliched messages of peace from the Koran. Fill the "game landscape" with Googled images of Muslim propaganda and sacred mosques while the Homicial Mohammeds blow themselves up in crowded schools, restaurants, buses, and markets.
Put that on exhibit. Go ahead. Be a maaaverick "artist." Show us how brave you are at offending all people of faith.
And, if I ever hear shrieks of "theocracy" applied to the United States again, I will simply re-cite this -- and ask how long the artist would survive if it were the Prophet and this exhibit was in Iran.
