According to the world-renowned wikipedia (grains of salt warning), here's some background on Karatzaferis:

He has referred to Jews as "God-murderers" (θεοκτόνους in Greek). He has asserted that "Hitler was a mere college-boy compared to the Jews". He has called for Greece to "reconquer" Istanbul, which he refers to as Constantinople, from Turkey within 5 years. He has promoted the myth that 4,000 either Jews or Israelis were warned to stay away from the World Trade Center on 9/11, and that, variously, no Jews or Israelis were killed at the World Trade Center. He has also claimed that 9/11 was planned and executed by Israel. He has defended Jean Marie le Pen, against the "Jewish pens that curse him. They are the same pens that curse and accuse us". In 2000, Karatzaferis claimed that the Protocols of Zion were being put into effect and that "the Pope and the Jews are conspiring against Greece". He has claimed at various times that 136 of Greece's 300 MPs are Freemasons, and that 100 MPs are "passive homosexuals with Albanian stallions". He is an ardent opponent of the so-called "New World Order", which is, he says, a plan to make Greece a puppet of the Jews...
