I think most people claiming a genocide is occurring are using a broad scope, like the conflict in Gaza since Oct 7 (if not something even broader), so it seems appropriate to look at the population change within that time period.
OTOH noone is claiming a genocide of Jews occurred from 1933-2025, so it wouldn't make sense to look at population change for that entire period.
The first claim is that genocide has been happening since 1948, the second claim is that it has increased in intensity in the last two years, both claims can be completely dismissed as fabrications by simply looking at the population growth of the nation that is supposedly being killed.
I honestly don’t know why you would bring up the fact that the Jewish population is climbing after the eponymous genocide was attempted.
Population numbers are very relevant as are the intentions, actions, and policies. The only people talking about and actually attempting to commit genocide are the Arab/Muslim colonists who have been attempting to colonize and genocide the native people for over 500 years. Most recently last week in southern Syria, before that was 2 months ago in western Syria, but before that obviously Oct 7th. Due in no small part to the IDF all these attempts have failed, but until the colonists either go back to the Arabian peninsula, where they came from or at the very least stop trying to kill their neighbors there will no peace.
