An interesting concept.
This was an accusation directed at Geert Wilders by one of his critics, during the controversy surrounding the recent failure to broadcast anti-Islamic cartoons as part of a political broadcast he planned to make.
I believe that the critic who accused him of "Using the truth as a weapon" was speaking on behalf of a Muslim group, but I cannot trace who this critic was. However I am intrigued by the idea that "Using the truth as a weapon" is something for which anyone should be condemned.
