An openly gay publicist who had formerly worked as a professor at Erasmus University, he had described himself at one time as "Marxist". He was a focus of controversy for his hostile views on Islam and his anti-immigration positions. He was opposed to Muslim immigrants such as Khalil el-Moumni, who he said refused to integrate into Netherland's society and formed a threat to the country's tolerant culture. He has been called a right-wing populist, but he himself rejected this label and distanced himself from right-wing politicians active in Austria and France. He could perhaps be described as a nationalist, but on cultural and not racial grounds.
