Four years ago, the US invaded Afghanistan and toppled its theocratic Taleban government. While primarily done as a means to an end (the end being getting Osama bin Laden - something they have spectacularly failed to do), the invasion was sold to the world partly on the promise that the new Afghanistan would be better than the old - free, democratic, and not run by theocrats.
Unfortunately, there's a contradiction between the last two - which is why there's currently a man on trial in Kabul for the "crime" of converting to Christianity. If convicted, he faces execution.
This is simply wrong. It's not wrong because he's a Christian and his oppressors are Muslims, or because he is facing execution (though that adds another layer of wrongness to it), but because religious belief is a fundamental expression of individual autonomy, a core part of who we are, and therefore something which no-one has any right to interfere in.
There's a strong argument that freedom comes from freedom of religion. Unless you're willing to accept that what people believe is their own business (or alternatively, between themselves and whatever gods you happen to believe in), then nothing else really follows. Freedom of thought and conscience is just freedom of religion writ large. Freedom of speech depends on an acceptance that being wrong is at worst stupid rather than sinful, and that therefore it is not a crime to disseminate "untruths". And once you accept that people have the right to think what they want and say what they want, it becomes progressively more difficult to deny them the right to do what they want as well. Unfortunately, by denying the freedom of religion, Afghanistan won't be able to tread this path. They may be able to find another way to freedom, but I'm not sure its one we can help them with.
