Free speech is the bedrock of liberty and a free society. And yes, it includes the right to blaspheme and offend.

As soon as something like Monty Python's 'The Life of Brian' appears with a Muhammad figure as the main lead, directed by an Arabic Theo van Gogh, the controversial late Dutch filmmaker, we will have taken an enormous step forward.

In Holland I have seen well-meaning, principled people blinded by multiculturalism, overwhelmed by the imperative to be sensitive and respectful of immigrant culture, while ignoring criminal abuse of women and girls.

My friend, the Dutch filmmaker Theo van Gogh, was murdered in 2004 for having been insufficiently reverent toward Islam.

Women covering their heads is traditional, but now we're seeing more and more women covering themselves from head to toe. This is said to be for religious reasons but it's actually the conflation of religion and politics - every political movement has its slogans, flags and dress.

The people who believe themselves to be on the left, and who defend the agents of Islam in the name of tolerance and culture, are being rightwing. Not just rightwing. Extreme rightwing. I don't understand how you can be so upset about the Christian right and just ignore the Islamic right. I'm talking about equality.

There can only be one answer to this hideous act of jihad against the staff of Charlie Hebdo. It is the obligation of the Western media and Western leaders, religious and lay, to protect the most basic rights of freedom of expression, whether in satire on any other form. The West must not appease, it must not be silenced. We must send a united message to the terrorists: Your violence cannot destroy our soul.
