If you're reporting the sale, charge tax

Definition of "fraud" not withstanding, no don't commit fraud of any sort.

But I think the decision to charge taxes on your products needs to soberly assessed when you know how that tax money gets used.

The requirement is being pressed onto your customers by the government, and they won't blame you for it. Nor do I, but I stand by my statement regarding the tax itself.

What you decide, and how you go about it, is up to you. And last point, I believe, is within the ethos of Bitcoin.
