While acknowledging the Basic Instinct star as an intelligent woman, PETA bosses fear the actress may need to work on her compassionate nature. And, after she was forced to apologise to China for suggesting the country's recent earthquake tragedy was "karma" for the way the nation treat Tibetans, PETA chiefs feel Stone might be ready to undergo medical tests.
"Given that millions of people... were killed, injured, and left homeless by the recent earthquake in China, everyone was shocked to hear you dismiss the devastating effects of this disaster," Contactmusic quoted the letter, as stating. "However, your cavalier attitude did not come as a surprise to us. We are used to the indifference that you flaunt and the callous remarks that you make about the suffering and death of the animals whose fur you wear so often.
"Scientific studies suggest that the prefrontal regions of the brains of people who lack empathy might be underdeveloped. Here's our offer: Would you allow PETA to pay for a scan of the prefrontal region of your brain to determine if comments and actions that seem to demonstrate a lack of empathy are the result of a physical defect?" the letter stated.
