Who has proposed that Holocaust denial should be "ignored," and what is the rationale behind this?

by AlmightyB

Reading a variety of books on Holocaust denial, I keep coming across vague references to historians who have claimed we should totally ignore it. Lipstadt mentions this in the start of Denying the Holocaust for example. Who has claimed this? Do some academics still support this line of thinking?

A LOT more can always be said, but this Monday Methods thread by u/commiespaceinvader goes into great detail regarding this topic.
