They literally and unironically quote liberty prime from fallout and think he's a cool tough American badass.

Here's a couple lines that didn't trip their trigger that maybe what theybwere consuming wasn't earnest.

"Democracy is non negotiable"

"American casualties: unacceptable. Overkill protocols authorized."

"Death is a preferable alternative to communism."

nah i'll give them halo, it glamorizes the child-kidnapping lady-goebbels that created the spartans (Dr. Halsey is perhaps internally conflicted but constantly proven to have made the 'necessary tough choices' to save the universe/humanity/etc., and i cannot stress enough how much the books and other media like halsey's journal in halo reach glamorizes being a child soldier to children), the covenant are basically a racist republican's idea of what Islam is, a fraudulent religious totalitarianism (the prophets know for a fact that the humans are the real Chosen Special Race, but lie to their people and say the Covenant is the Real Chosen Special Race) complete with suicide bombing slaves (grunts), and the Real Ancient Threat, the Flood, is an obvious allegory for Communism that the Christians (humans) and Muslims (aliens) have to come together to destroy - after, of course, the Muslims/Covenant overthrow their corrupt rulers (with the help of the human personification of the American Navy, Master Chief) to join the Christians/Humans.
