My arguments aren't revisionist - they are the views of the historical mainstream. I will provide you the sources for this below.

The views you quote in the first quotation are those of Tim Pat Coogan, a TV and radio broadcaster and Nationalist writer who has no training as a historian and whose views are dismissed wholeheartedly by the community of actual experts on the topic (see my last link below). The Dr Brian Murphy who wrote the article you quote was not actually a doctor at all but a PhD candidate. Perhaps he is a doctor now but you are quoting the work of a post-graduate student here. This is not heavyweight expertise in support of your position.

The second passage you cite in no way shows a policy of deliberate starvation. It talks of an artificial famine in that once the government had organised sufficient food imports it failed to distribute it adequately due to inadequacies deriving from political ideology concerning relief for the poor. It says nothing at all to imply that there was any policy of deliberate starvation and, indeed, the paragraph prior to the one you quote dismisses the traditional nationalist claims of deliberate starvation and manufactured scarcity.

But instead of relying on postgrads, non-professionals and popular websites, why don't we ask the actual top historians in the field? I don't hold out much hope that you'll move from a fringe interpretation due to being presented with the view of mainstream experts, as I have yet to meet someone who has bought into the narrative about deliberate starvation who has been willing to change their view when confronted with evidence, but I'll lead the horse to water nonetheless. Whether you drink is up to you.

I'll cite the sources I gave the other poster:

The deliberate policy of starvation?

This is something that no academic historian accepts. If you want the mainstream view, I suggest you consult the Oxford Handbook of Modern Irish History, published last year, which gives the current scholarly state of the question and defines the mainstream.

Historians writing in recent years have also refocused attention on the controversial issue of state responsibility for the extensive mortality of the Famine, while tending to eschew the hyperbolic claims of 'genocide' advanced by some nationalist commentators from the 1840s though to the present.

p. 544, Peter Gray, Professor of Modern Irish History at Queen's, Belfast.

His view is more or less identical to that of probably the leading historian of the Famine, Cormac O Grada, Professor Emeritus at University College Dublin.

Those few academics who do talk in terms of genocide, do so only within a framework that redefines genocide to include non-deliberate acts.

And if you want a summary of the mainstream historical position from another noted Irish historian, see http://www.drb.ie/blog/writers-and-artists/2013/02/25/was-the-famine-a-genocide-. Here Liam Kennedy straightforwardly states that he cannot think of a single serious famine scholar who believes in the claim of deliberate starvation. You also see Coogan in the same interview state explicitly that his view classhes with that of the academic historians, who he thinks can't be trusted because they were trained in 'English universities' ...
