Another example:
Say you're arguing with a guy who says that Paul Ryan is smart because his budget plan clearly shows it would reduce the deficit.
So, in DH7, you would first point out that Ryan's plan is build on two magic asterixes which assert, rather than prove, that revenues will be increased over time, giving no means of why or how that would happen. You then correct his plan to show an actual working budget based upon austerity and supply side economics. You then destroy that improved budget by showing that austerity measures in a liquidity trap are retarded, using Neo-Keynesian economic theory.
