One need not invoke 1940s Europe to discuss contemporary fascism.
Indeed, to do so only serves to alienate those sympathetic to cause for liberation, while at same time ceding ammunition to one's opponents, even as it empowers fascists of another ilk.
Today's fascism is not the fascism of WWII. Its ethnocolonial roots predate those events by decades and its geopolitical dimensions transcend that moment in history by ideology.
Conflating today with yesterday only ensures we learn from neither.
