fascism is more specifically for ethnonationalists, not just pro-capitalist right wingers. fascism is compatible with capitalism and so there's overlap.
anti-imperialists oppose ethnostates and colonialism and that's why there's so much overlap between zionists and fascists in opposing 'tankies'. support for israel (a jewish ethnostate) is support for fascism regardless of other politics.
the question you pose feels like setting up the deflection of 'see you just call everyone you disagree with fascist'
