"Fascist" began as a neutral description of political-financial relationships and was later made into a household slur by the Soviets to take the heat off after people started likening them to Nazis thanks to their short-lived military alliance, their shared "-ism word", and their common interest in techniques of political oppression (search term: "Gestapo–NKVD conferences"). In this context, there is no logical connection to philanthropy much less to "white supremacy", a term that's almost always used monomaniacally.
