I'm not arguing that more deflation is better, or that the current deflation rate of bitcoin is good. I have seen first-hand that it is not. My claim is that both high inflation and high deflation are bad, and that both low inflation and low deflation are tolerable.
One thing you have to realise is around that time the federal reserve was repeatedly trying to manipulate the price of Gold, Bitcoin can't be manipulated so easily and also Gold is used for a myriad of other things besides a currency, you can't claim you have seen proper deflation in action because there hasn't been a currency from what I'm aware of in existence that has been specifically developed with deflation in mind, that's where Bitcoin comes in.
