"But even the Fischer apologists had to throw up their hands when he took to the Philippine airwaves on September 11, 2001. In an interview broadcast this time by Bombo Radyo, a small public-radio station in Baguio City, Fischer revealed views so loathsome that it was impossible to indulge him any longer. Just hours after the most devastating attack on the United States in history, in which thousands had died, Fischer could barely contain his delight. "This is all wonderful news," he announced. "I applaud the act. The U.S. and Israel have been slaughtering the Palestinians, just slaughtering them for years. Robbing them and slaughtering them. Nobody gave a shit. Now it's coming back to the U.S. Fuck the U.S. I want to see the U.S. wiped out."
"

Fischer has had some deeply controversial political views, including a rabid and unapologetic anti-semitism.

In 1984, Fischer wrote to the editors of the Encyclopaedia Judaica asking for his name to be removed from the publication on account of him not being Jewish ‏² (http://home.att.ne.jp/moon/fischer/list/p_42/42_0.ht...). By Jewish Law standards he would be considered Jewish since his mother was. In recent years he has given interviews with Pablo Mercado and Grandmaster Eugenio Torre on the Philippine radio station Radio Bombo, in which he has confirmed his fanatical anti-Semitism - among other things, he has spoken of a worldwide Jewish conspiracy, and has denied the Holocaust happened.
