Sigh. And no-one else in this debate has ever used exaggerated language.
I have no idea if Nick would reject an argument that had any
exceptions at all, but I don't think it's unreasonable to ask that
people at least *try* to formulate an argument that demonstrates that
the two existing ways we have are inferior to the proposal. Stating
that you're not even willing to try is hardly productive.
