I tried to ignore it but I cannot - this is a ugly comment. And for hackernews it's devoid of fact or even interesting opinion. It uses a familiar tactic commonly associated with bigots: don't agree that there's a global Zionist conspiracy to rule the world? - the Jews are clearly too clever for you. Don't believe that the Roma are immigrating en-mass with the plan to displace the natives? - the Gypsies are too clever for you. Rounded off with the suggestion that the Irish as a whole have obvious negative personality traits.
And your theory is as outlandish as any global Jewish conspiracy stuff. An entire nation of people from across the political and social spectrum have connived to defraud the rest of the world based on a sneaky tax-policy plan enacted over 3 decades ago which has survived 2 European treaties, 5 changes of government and requires the entirity of the "Irish" to be liars. It's an ugly comment with even uglier undertones.
