What is caught in the "Holocaust denier" net does not consist solely of people who outright deny it occurred - there are many shades of grey, opinions in this realm are highly dimensional.
This isn't to say that censorship in this case isn't justified or fairly optimal (in achieving gross human happiness), but if a cause is just and righteous, it shouldn't present a highly distorted representation of objective reality, or refuse to vigorously defend it's assertions. If your case is correct, "in fact", it should be defensible in the context of a non-simplified representation of reality.
If proponents of an ideology (censorship, in this case) are not willing or able to do that, then I would find it more palatable if everyone was just honest and acknowledge that a very rough approximation is being done, for reasons X,Y,Z - I think a fine argument could be made, and this way no fibs are being told.
