The ones you have quoted have specifically blamed Te British policy for the effects of Famine

Not true.
"However, given the scale of the problem and the acute nature of the crisis once the harvest had failed for a second time in 1846, there was little they could do."

There is a dispute, she is part of it, and that is my whole case.

You are wrong to deny it, and you have made yourself look silly over it.
