What describes a similarity between fascism and communism during the 1930s?

Both fascism and communism in the 1930s sought to establish totalitarian states that suppressed individual freedoms and dissent in favor of a collective ideology. Each system promoted a strong, centralized government led by a single party, aiming to mobilize society for a unified purpose—whether it was the supremacy of the nation in fascism or the establishment of a classless society in communism. Additionally, both ideologies employed Propaganda, censorship, and state violence to maintain control and eliminate opposition. Despite their ideological differences, they shared methods of authoritarian governance and a rejection of liberal democracy.
