That fact alone lets me believe she may have a point.
The thing is that some people on both sides of that argument are a lot more convincing than others. No one can seriously deny that there was the mass murder of Jews and people from Jewish backgrounds in the Ukraine, Belarus and parts of the Baltic countries and Poland by shooting as Jews and people from Jewish backgrounds and not as partisans, etc. Even Alfred Rosenberg- no friend of Jews as Jews- complained about this (he was later hung by the Allies because his propaganda was blamed for how things worked out). Other issues are more complex.
Another problem is that most of the scholarship done by both sides has been done by people who have strong political and/or emotional investments with one "narrative" or the other which does not necessarily dismiss their work but it is something you have to take into account. Than there is the way it is used politically, very nimbly and sometimes in even contradictory ways, by contemporary elites which means it has moved on from being solely or even mainly about the actual events of those times. It is unclear whether the new laws will prohibit the critique of that usage which is what is really annoying me.
It is also extremely annoying for me that we have an official "Holocaust Rememberance Day" here but no offical rememberance day for An Gorta Mor/the Irish Holocaust.
