That doesn't make him a holocaust denier. And we agree, no live holocaust happening right now.
EDIT: (took a while to find the website but here's a quote from Norman)

Haunted House - Norman Finklestein
I don't know the context behind his endorsement of Irving, but Norman appears to be a complicated man so I don't know exactly what he's referring to, possibly that Irving had some good insight into WW2 from the Nazi perspective? Dunno. But I dont think he's denies that the holocaust happened.
Douglas Murray is a soundbite merchant and shouldn't be listened to. Especially after he shat his pants when Piers offered him to debate Norman.
Happy for people to have an opinion on Norman, as you clearly do but labelling someone a holocaust denier without concrete proof/more rational explanation is a bit silly, especially as he talks about his parents surviving the holocaust.
