Christians Under Attack

Wilders has argued that his views of Islam are supported by expert and academic analysis, and that speaking the truth cannot be a crime. He says the charges against him are an attack on freedom of speech

But at the second hearing of his closely watched trial, prosecutors countered that there is no general agreement about the nature of Islam, and Wilders's statements are opinions that cross the legal threshold.

However, prosecutors have dropped one charge against him, of insulting a group on the basis of its religion, noting that his statements have been mostly directed toward Islam as an ideology, rather than Muslims.

He is still charged with inciting hatred and discrimination against Muslims. Under Dutch law, it is illegal to insult or incite hatred against a group of people on the basis of gender, religion, race or sexuality.

Prosecutor Birgit van Roessel said: "What he puts forward is, and remains, his individual opinion, and just like with any expression of opinion, we can test whether it falls under the right to freedom of expression or whether it is a transgression of the criminal code."

The case against Wilders is based on dozens of public statements. Typical among them were views he published in an opinion piece in the national newspaper De Volkskrant.

"I've had enough of Islam in the Netherlands; let not one more Muslim immigrate," he wrote. "I've had enough of the Koran in the Netherlands: Forbid that fascist book."

As recently as August he repeated his view that Islam is inherently violent and backward.

In a television interview, he said: "Our culture, which is based on Christianity, Judaism and humanism, is better than the retarded Islamic culture, and this is tough to say, but it is true. It is a violent ideology like communism and fascism and we should deal with it that way."

Wilders - who polls suggest is the Netherlands' most popular politician - denies wrongdoing. He says his opinions are protected by freedom of speech and endorsed by more than a million people who voted for him in national elections last June.

Without addressing any of Wilders's specific remarks, Ms Van Roessel said freedom of speech has limits.

She said: "You can expect a politician to be aware of the impact of his words, and in any case, the legal limit may not be crossed, no matter how important it may be to address supposed problems and to contribute to matters of general interest."

Prosecutors had initially declined to act on complaints and press charges against Wilders at all.
