On the right, in his usually very funny comic strip B.C., Johnny Hart, an evangelical Christian, did an Easter cartoon that offended many Jews. It showed a menorah fading into a cross, accompanied by Jesus's dying words and an open tomb symbolizing his resurrection. Hart insisted he was trying to honor Jews as well as Christians, but the burned-out candles of the menorah seemed to tell Jews that their religion was defunct.
On the left, Ted Rall regularly produces wretched-excess cartoons. One dismissed Colin Powell and Condoleezza Rice as "house slaves." Other Rall strips attacked some widows and relatives of 9/11 victims, as well as the widow of Daniel Pearl, the Wall Street Journal reporter kidnapped and murdered by fanatics in Pakistan. Rall depicted Pearl's widow as a publicity hound, making pointless and tacky appearances on many shows. He depicted her at a microphone, saying, "It's a bummer that they slashed my husband's throat -- but the worst was having to watch the Olympics alone."
Rall, who positions himself as a sort of Howard Stern of cartoons, has naturally attracted many detractors. I don't much like his work, but there are many columnists and authors who go too far without attracting posses determined to eject them from the local paper. Let's avoid sensitivity censorship. Let them be.
