A suspended sentence of eight weeks was passed for the third charge.
She appealed the conviction but, after hearing the evidence at Southwark Crown Court, Judge Christopher Hehir upheld the convictions on Wednesday.
In his judgment, Judge Hehir said that the court did not have to entertain “absurdity or fiction” in cases of Holocaust denial, adding: “We take judicial notice of the fact that the Holocaust occurred.”
He said: “She is a Holocaust denier... She is manifestly antisemitic and obsessed with what she perceives to be the wrongdoing of Jews.. She appears to have lost all sense of perspective."
Addressing her song (((survivors))), in which she mocks Anne and Otto Frank to the tune of Hava Nagila, Judge Hehir said: “It is by no means an exaggeration to call this song disgusting.”
He said: “She positively intended to be grossly offensive to Jews."
The case against Chabloz began as a private prosecution by Campaign Against Antisemitism (CAA), which the Crown Prosecution Service then took over.
CAA chairman Gideon Falter said: “Alison Chabloz is no patriot and her actions defending the Nazis and claiming that the Holocaust was a fraud seek to defile their sacrifice."
