Bush 'worship' at Shinto Temple troubles Christians in Japan and U.S.

"It was an act of idolatry," says Kiyomasa Akashi, with Logos Ministries in Tokyo. "Even worse, it was an official, public idol worship," Akashi says. "He did bow before the shrine where the Meiji Emperor is enshrined as a god."
Some people get all bent out of shape whenever Bush, as President of a country that guarantees religious freedom, show respect for other faiths.
That article claiming Bush is an idol worshipper is just so petty and small minded.
