Ahem.
If I may interject my 2p worth (0.003c at current exchange rates). Deborah Lipstadt, she who brought low the mighty David Irving (yay, go Deb, go Deb, go Deborah!) refuses to debate the Holocaust with Holocaust deniers.
Why?
Because, as she states, there is no "other side" to the debate. Those who want to debate are actually out to further their own agenda, not to honestly debate an issue.
I have to say that there are parallels here, with those who intend to shoehorn the facts into their interpretation of reality vs. those who deal with reality as is.

And having thrown all that into the pot, may I observe that the Creationist/Evolutionist battle/intense discussion/spat/mild disagreement only seems to be an issue in the US. Over here in the UK it isn't a worry. Well, not yet ...
