When government says what the "true religion" is.

Tony Blair spoke out yesterday about stamping out the virulent version of Islam that (apparently) led to the 7/7 bombings:

Talks are to begin on bringing in new laws covering preparations for attacks and to make it easier to deport people trying to "incite hatred", he told MPs.

The "moderate and true voice of Islam" had to be mobilised, he said....

"This is not an isolated criminal act we are dealing with," he said.

"It is an extreme and evil ideology whose roots lie in a perverted and poisonous misinterpretation of the religion of Islam."...

Those behind the bombings were perverting the teachings of Islam, he argued....

Of course, I understand his motivation for saying this, and I agree with his opposition to a dangerous, violent ideology, but how can he say what the true intepretation of a religion is? I realize Britain does not have as robust an approach to the separation of church and state as we have, and I can see the role of government promoting the more socially beneficial versions of religion -- quite apart from the truth -- but who is Tony Blair to say what is the "true" version and what is the perversion?

If the bombers' version was in fact the more accurate interpretation of the Islamic tradition and moderating fundamentalism was the perversion, he'd be for the perversion, wouldn't he?
