The Irish Famine was a genocide, because it was intentional. I should’ve clarified I mean that famines can be genocides, but are not inherently genocidal.

I’ll note that your own source says in the very first line:

While scholars are in consensus that the cause of the famine was man-made, whether the Holodomor constitutes a genocide remains in dispute

Here's a quote from the Irish Famine (same source: wikipedia)

Virtually all historians reject the claim that the British government's response to the famine constituted a genocide, their position is partially based on the fact that with regard to famine related deaths, there was a lack of intent to commit genocide.

So you have two options:

1. You either accept both as a genocide

2. Or you basically pick-and-choose based on whichever country was responsible for the genocide.

My guess is that you'll take the second option.
