You could replace this chart with a different Western nation and its equivalent parties (or at least scales between the strong left and strong right among the population) and the numbers would mostly match up. It seems to be a pattern, even in Amerikkka, too, at least in regards to the older generations voting more conservative and siding with status quo generally while the new generation of voters have been radicalizing towards the fascist right (especially among young men) as well as the socialists/progressive left (especially among young women and non-binary).
