I'm waiting for an apology from Robert Spencer

Robert Spencer received a letter from Vlaams Belang, explaining themselves with utmost politeness and full rational explication of data with regard to his McCarthyesque vilification of them.

He has also had opportunity to read the evidence from the Center for Vigilant Freedom, which offers detailed, cogent arguments to exculpate Filip Dewinter and Vlaams Belang.

Spencer owes Dewinter and Vlaams Belang an apology.

Why has he not published one on his site, Jihad Watch?
