Wow, always, I'm shocked I have to freaking spell it out for you.
Using exaggerated caricatures: nazis did that to the jews.
Using fearmongering instead of facts: fearmongering is the go to place when you want people to act like brainless sheep instead of thinking for themselves. A position using fearmongering instead of facts and logic is pretty much a blatant admission that you're arguing for something stupid or ethically wrong, if not both.
“Monsters now living in cities pretending to be equals while actually oppressing them.” The nazis said the exact same thing about jews.
“Monsters control all the governments.” The exact same argument as those who claim that Pres Obama is a muslim actively trying to destroy America, the same argument racists made about “blacks having too much influence in politics” while they were woefully under represented. The same argument made in anti-communist hysteria by McCarthy.
Real schools are about education, not propaganda. Propaganda, by definition 'information, especially of a biased or misleading nature, used to promote or publicize a particular political cause or point of view." The game itself calls the film propaganda not a documentary.
Propaganda is about indoctrination, cults do that, lying politicians do that, education involves facts. Did you somehow miss that there wasn't single fact used when finding out the militia's view of the world? My guess is because there is nothing actually factual about their point of view, but hey I might be surprised.
The PC says "They didn't even have to fight to take our cities, we just let them in," That means the militia is upset that the monsters are buying houses and sending their kids to school and getting jobs as if they were people. How dare they! If you need it spelled out to you how that's something racists have complained about since the dawn of time then you fail history forever.
“They’ll pretend to, but it’ll only be a ruse to try to conquer us,” some people said the exact thing about the Japanese after world war 2. I don’t know about where you are, but I don’t have a samurai master threatening to make me commit suicide if I don’t get to the slave camps fast enough.
“We cannot allow ourselves to tolerate their presence. Not even for peace. Because whatever peace we form, no matter how much we want it, would never last. They will never stop. They will keep fighting against us; either conquering us through violence, or stripping us of our rights through our own courts.” Do you really need it spelled out to you that the miltia member is proposing genocide, and that his logic is “If we don’t kill them all then they’ll kill us first.” That is pretty much the verbose version of “It’s us or them,” the standard for genocidal madmen everywhere.
And did you miss the fact that their position contradicts itself? If the monsters control the governments, then they control the courts by definition, and if the monsters intend to wipe out humanity than humans don't actually have rights. If they are paranoid racists, why then it makes sense, they're arguing "How dare you take away our right to ignore the rights of others?" the rallying cry of those who think "I'm oppressed by someone elses mere existence" is actually solid thinking.
Genocidal monsters would make people vanish in the middle of the night, not take someone to court because “he won’t let me kill him” isn’t a valid legal complaint.
" You would never give them concessions of any kind, no matter the situation?" No concession, as in not letting their kids go to the schools of their choice, being allowed to practice their religion, not allowing them to keep their jobs, not allowing them to live where they want, not allowing them to get married, hell not even the right to live in peace without being murdered.
Did you not notice the implication of the militia having a legal division? If the governments are really controlled by monsters, and humanity is really in a battle of survival to the very death with another race, what good would lawyers do? Absolutely none.
If one is trying to disenfranchise an entire race and in no doing set back civil rights two hundred years, well then that legal division would be kept hopping.
