"Fascism /ˈfæʃɪzəm/ is a form of radical authoritarian nationalism[1][2] that came to prominence in mid-20th century Europe. Fascists seek to unify their nation through a totalitarian state that promotes the mass mobilization of the national community,[3][4] relying on a vanguard party to initiate a revolution to organize the nation on fascist principles. Hostile to liberal democracy, socialism, and communism, fascist movements share certain common features, including the veneration of the state, a devotion to a strong leader, and an emphasis on ultranationalism, ethnocentrism, and militarism."
Yeah, Singapore is nothing like that. The fact that 20%+ of its population are immigrants, and how it embraces immigration, disproves your pet theory. Singaporeans don't have statues of their leaders in their homes, and they're not mobilizing anyone to fight some greater evil. Singaporeans are more devoted to their iPhones than their prime minister.
Using "fascism" loosely is just ignorance.
