While I don't agree with the gp's vehemence, saying that a certain statement is "almost literally equivalent to Holocaust denial" doesn't mean accusing someone of Holocaust denial- but of something similar.

Btw, accusing someone of something should or should not be a bannable offence independently from the accused ethnicity or religion. You don't want to have classes of people who can or cannot be accused of something on a "racial" basis, do you?
