I think Brad might have touched a raw nerve. Brad is professionally qualified to analyze, compare and contrast Walker's Plan and the 50/50 Plan; Dermot is a journalist, but has a better than passing understanding of government spending but nowhere near the expertise of Brad. 
I was a little surprised to see Dermot make the inflation proof comment that he did because it appears to be a contradiction to the statement Angela Roddell, head of the PF, made regarding inflation proofing the PF; the fund self-inflation proofs, and on this most everyone except Dermot the Journalist, agrees. 
From here most of what Dermot comments on goes downhill and he resorts to chastising Brad because Dunleavy supports a different approach to resolving our fiscal situation. The important thing here is that we do something, but there's no requirement to do it Walker's way, but the best way with the least impact on our economy. Dermot, as usual, you strike on  this one!
