Discuss and please provide simple easy to understand examples so that a 5 year old would be able to understand exactly what fascism is, once that is established we can move on to the more difficult aspects of it.
I will start with the common wiki definition of what fascism is and we can build on that:
Fascism ( /ˈfæʃɪzəm/) is a radical authoritarian nationalist political ideology. Fascists seek elevation of their nation based on commitment to an organic national community where its individuals are united together as one people in national identity. They are united by suprapersonal connections of ancestry and culture through a totalitarian state that seeks the mass mobilization of a nation through discipline, indoctrination, physical training, and eugenics. Fascism seeks to eradicate perceived foreign influences that are deemed to be causing degeneration of the nation or of not fitting into the national culture.
This definition, while a good one, is complex and vague so lets dumb it down and make it more digestible and talk about real world actual experiences that one can expect in a fascist state.
