I stopped talking to people about the film because I discovered that most of them didn't see it as satire or think the book (which they read as teens) was proto-fascist.
The movie is an obvious satire. I've never understood how people get proto-fascism from the book. Even assuming it isn't a satire itself (and I could be convinced either way) it dwells on the military in a conservative society but the society it describes is also a democracy that doesn't even let active-duty military members vote.
