Since he keeps insisting that the Holocaust requires more research — until it’s “proved” it didn’t happen of course — it’d be nice if he was asked if Muhammed existed or whether the Koran makes any sense. There are mountains of evidence that the Holocaust happened (millions of witnesses, documents, bodies, confessions etc). By comparison, the evidence that Muhammed existed is, shall we say, scant. It’d be fun to ask him if this is a valid field of research.
