The conference is organized by the international alliance Stop Islamization of Nations (SION), founded by Pamela Geller, who together with the extreme right group English Defense League organised a so-called counter jihad meeting in Stockholm this past weekend.
Asked by Swedish Radio News whether he finds it problematic to be linked to such a group, Vilks said, "no, I don't see a problem. If people want to link me and my work to this or that, they can. I do no see Islam as a big threat to the West."
