Given the astonishingly bad reasoning behind those self-same ideas and the damage they have indirectly caused the US domestic economy - I'd say it's a well deserved potshot (compared to some of the vitriol directed at socialists).

Fair enough, that is your opinion. But why point to a badly written smear-piece full of "ad hominem" attacks.

Write what exactly do you find wrong with such reasoning.

Or maybe read the other point of view and see if it maybe makes more sense than you originally though...
