According to my book on the subject there is widespread conviction in the Irish diaspora that the inadequacy of the official relief response from about mid 1846 onwards was the result of a deliberate policy of genocide on the part of the British. A view not helped by idiots writing smug comments in The Times such as "In a few years more a Celtic Irishman will be as rare in Connemara as is the Red Indian on the shores of Manhattan."

I think there is, indeed, a subset within that community that believe the blight was caused by the British.
