To say that you are willing to listen to holocaust deniers but will not automatically assume there is no holocaust is the same as to deny the holocaust and be a nazi except that time when Deborah Lipstadt said that there was no girl that gave a boy an apple over a fence even though it was real in his mind except when other people said the same thing they were holocaust deniers
But If you say this is criteria for whobis a holocaust denier then you are a holocaust denier by the mainsteam criteria
