Once upon a time tolerance was the power that kept lovers of competing faiths from killing each other. It was the principle that put freedom above forced conversion. It was rooted in the truth that coerced conviction is no conviction. But now the new twisted tolerance denies that there are any competing faiths; they only complement each other. It denounces not only the effort to force conversions, but the very idea that any conversion may be necessary. It holds the conviction that no religious conviction should claim superiority over another.
