"Racism is a form of hate."
To defend past racism as not being racist, as you have done, "Political not racist" is to lend support to racism - doesn't come any more complicated as that.
To describe Irish and Irish American people in terms such as "Not surprising when generations of school children have been brainwashed to believe Britain should be blamed, keeping hate alive. Irish schools at least since 1922 and NY State schools since 1996 by decree. Massachusetts?" is a racist attack on those people and an insult to a large number of members of this forum
If this is not your posting, and someone has faked the posting I withdraw my accusation and apologies (or maybe that should be "grovel") - other than that, you have made a racist attack on millions of people - it doesn't come any more complicated than that either.
As far as your spurious claims on historians, every single one I have read holds Britain as culpable for the the Famine - not one has denied that their policies brought about millions of deaths - not one single one.
Not one has attempted to claim that; the closed workhouses and warehouses, the financial corruption surrounding famine relief, policy of exporting food out of starving Ireland, the mass evictions, the enforced emigrations; were not responsible for the million plus deaths and the depopulation of Ireland.
If you have an example of one historian denying any of this, please produce it - I have failed to find it.
What the vast majority have said is that Britain's culpability was due to callous indifference in putting the interests of The British Empire before before the lives of the Irish - all but one (a British historian based in Belfast) have claimed that this was an inhuman decision and that there were alternatives.
All this has been specifically stated by the people you have produced.
The only thing in dispute is whether or not this was a deliberate act aimed at the Irish - deliberate genocide.
As far as Britain's representative of Irish policy, Trevelyan, there is no question - he hated the Irish, he believed the Famine to be "God's retribution", and he urged a policy of 'emigrate or starve' - that is the policy Britain adopted - that is their culpability - it never becomes more complicated than that.
I haven't read enough to make up my mind one way or the other as to whether it was deliberate, or just Imperial profiteering, but it is one or the other - or maybe a mixture of both.   
You refuse to address the actions taken by the British government - you have been requested to do so several times.
You refuse even to acknowledge Trevelyan's advice to the British Government - you have been requested to do so several times.
Until you do both you have no case - one more time, it never becomes more complicated than that.
Have a good day
