Every time I went on TV I got a threat.

In a sense, my grandmother was living in the Iron Age. There was no system of writing among the nomads. Metal artifacts were rare and precious.... The first time she saw a white person my grandmother was in her thirties: she thought this person's skin had burned off.

This was not an attack by a mentally deranged, lone-wolf gunman. This was not an 'un-Islamic' attack by a bunch of thugs - the perpetrators could be heard shouting that they were avenging the Prophet Muhammad. Nor was it spontaneous. It was planned to inflict maximum damage, during a staff meeting, with automatic weapons and a getaway plan. It was designed to sow terror, and in that it has worked.

Americans have always welcomed people of all backgrounds, religions, and races. It's a spirit of tolerance, now energized and amplified by the cult of multiculturalism.

By declaring our Prophet infallible and not permitting ourselves to question him, we Muslims had set up a static tyranny. The Prophet Muhammad attempted to legislate every aspect of life. By adhering to his rules of what is permitted and what is forbidden, we Muslims supressed the freedom to think for ourselves and to act as we chose. We froze the moral outlook of billions of people into the mindset of the Arab desert in the seventh century. We were not just servants of Allah, we were slaves.

Unlike the United Kingdom or the Commonwealth, the umma, or Muslim community, has no symbolic leader, let alone a formal one.

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