From today's New York Times Editorial:
With the religious right clamoring for more religious iconography in public spaces, it is understandable that the court might have shied away from a dramatic ruling that would have heightened what is already a strong antagonism toward the judiciary among some conservative groups. Ceding some ground on Ten Commandments displays may seem like a way to keep the peace. But as our country becomes more religiously diverse, putting one faith in a privileged position is likely to create more religious strife, not less. As with so much else, the founders, who came up with the idea of a clear wall of separation between church and state, had it right.
Its one thing to agree with the opinion and make an argument that the interpretation of the First Amendment should change with the ages, but no one seriously believes that it was the founders who "came up with the idea of a clear wall between church and state" do they?
