Parent doesn’t say that they manufactured blight but that they manufactured famine.

This is also incorrect although they did preside over one and were reluctant to intervene for a variety of reasons, some economic and some philosophical.

Edit: and just to add, it was certainly not an attempt at genocide.

The blight in itself of course was not manufactured, however the policies that led up to the total dependency on one type of crop never failing, and the botched emergency reponse; was.

However, this famine is of course, not even a tear in the sea compared to the holocaust, which remains the most horrific act ever, forever; and every other act past or future will only be a tiny fraction of the depth of its importance. History begin and ends with the holocaust the plight of the Jews.

If you mean the disease, no.

If you mean blight as in "a thing that spoils or damages something", that something being the Irish substinence, they absolutely did. Read some history.

And since a million died, it's not exactly laughing matter to joke about.
