Mr. Obama’s words at a White House dinner celebrating the Muslim holy month of Ramadan were simple and forceful. “Muslims have the same right to practice their religion as everyone else in this country,” he said.

Republican ideologues, predictably, used his statement as one more excuse not only to attack the president but to spew more of their intolerant rhetoric.

Newt Gingrich, who has been beating this drum for weeks, accused the president of “pandering to radical Islam” and said the mosque would be a symbol of Muslim “triumphalism.” We were hesitant about repeating those comments here. But the country ignores such cynicism and ugliness at its own peril. Make no mistake, the rest of the world is listening.

Like President George W. Bush before him, President Obama warned against linking all followers of Islam to terrorists. “Al Qaeda’s cause is not Islam — it is a gross distortion of Islam,” he rightly said. It is our tolerance of others, he said, “that quintessentially American creed,” that stands in contrast to the nihilism of those who attacked us on Sept. 11, 2001.

We wish he hadn’t diluted the message the next day, telling reporters that he wasn’t commenting on “the wisdom of making the decision to put a mosque there. I was commenting very specifically on the right people have that dates back to our founding.”

He would have done better if he had explained the wisdom of going ahead with the project, which developers said is intended to bring Muslims and non-Muslims together. In addition to a place of worship, it would have a pool and performing arts center. They also have said they want the board to include members from other faiths — a promise they should take care to keep.

Too many Republican leaders are determined to whip up as much false controversy and anguish as they can, right through November. Some Democrats will cave. We were disturbed on Monday when a spokesman for the Senate majority leader, Harry Reid, said that Mr. Reid “thinks that the mosque should be built someplace else.”
