Well that's the funny thing about him. He constantly tries (and sometimes succeeds!) to ban lectures etc. that criticise him too much. When the NRC Handelsblad, which is probably the best newspaper in TN, had a not-so-positive article about the PVV he called the paper a gossip magazine, purely longing for sensation etc. The PVV usually get their articles from the Telegraaf, which is known as the biggest sensation paper in TN. If Kaddafi killed another 100 civillians and Britney Spears broke a fingernail, the fingernail would probably be on the front page.
So Wilders' notion of free speech: free speech, but only for me.
