Holocaust Denial up worldwide in 2007

It's not clear to me that it was significantly up over 2005, but there's more:

The annual report, "Holocaust Denial: A Global Survey - 2007," published by the Washington-based David S. Wyman Institute for Holocaust Studies, found that Holocaust-denial activity was up worldwide, following a drop in 2006 due to the imprisonment in Austria of leading denier David Irving.

Curious that the arrest and release of a single individual would lead to noticable changes in Holocaust denial worldwide. Via Deborah Lipstadt.
