Derrick,
Jim's original view,
"No they(historians) don't(dispute blame) - a tiny handful of your fellow Empire Loyalists attempt to defend British policy by saying (as Mrs Pinochet did) that there was no alternative to giving priority to the Imperial economy rather than feeding the starving Irish.
Not one single historian has ever challenged the facts of the Famine"

Two days ago, a U turn,
"There are two views of the Irish Famine - one that it was a natural disaster in which nothing could be done and no blame can be attached - the "revisionist...."

Now another U turn and he is back to denial.
Ask him if he accepts that there are revisionist historians who dispute blame.
