I used to teach English III and IV in a 90% Hispanic school and I always used school itself as a redpill.
The way I taught my class was by putting forward the values of the first amendment and the free market.
For the freedom of speech, I told my kids that I would never send them to the office for what they say to me. The example I would give is, "if you said to me, 'you're fucking stupid, do you know what I'll do? I wouldn't send you down to the office and get you quarantined off to a cubicle for the next week like all the other teachers who can't handle criticism, I'll ask you, why, because I may be wrong, and you could very well improve how I teach.'"
And as for homework and classwork, I'd explain, "how many hours a week is a full time job? 40, right? That's also how many hours you go to school every week. That's no coincidence. School was designed to prepare you for the workforce. Now, when you graduate and get a job, when you wake up, do you HAVE to go to work? Of course not. So what sense is there in hounding you for classwork? Additionally, if you don't like your job, can you quit? Of course. I would like to prepare you for that world, but in doing so, I have to give you the opportunity to fail. If you don't want to listen to my lessons, that's your choice. If you don't want to do classwork, that's fine too. The only thing I ask is that you allow those who do want to do these things, to do them."
I'd also explain things like voluntarism and compulsion and go over events like the white feather movement during WWI where women would shame men into joining the British military and fighting WWI. After that I'd have them evaluate whether the White Feather Brigades were more or less ethical than a draft, and whether or not women should be included in the draft.
I also taught them about the Soviet Union, and Solzhenitsyn while we read through 1984. I made parallels between authoritarian states and the school system.
Surprisingly, many kids don't know was communism is, but are very desperate for an answer. The short answer I give them is, "imagine school, but you don't go home at 4 o' clock." My long answer of course involves teaching about property rights and having the right to keep what you earn, vs. working for the benefit of others and not being able to tell your boss no, much like how you can't tell a teacher no without some kind of repercussions.
I'd point out the hypocracies of the school system, like how teachers only work 180 days a year, 6 hours a day, yet they get paid the same amount as a full time worker.
I explained progressive tax rates, and how because of them and college costs, by the end of their lives, a plumber and a doctor make the same amount of money.
I teach them incentives and how taxing people more as they make more money would discourage them from working hard.
Then I show them the flat tax and ask which one is fair.
I taught them about the slave trade and how it differed from the Religion of Cuck™ic slave trade, and I'd also teach them about indentured servitude.
After teaching them about the Religion of Cuck™ic slave trade, I'd ask them "The Religion of Cuck™ic world enslaved more than the Western world, but there aren't very many blacks in countries like Saudi Arabia. Why is that?" I'd then tell them about how all males were turned into eunuchs upon entering slavery and how 10% of them all died from infections.
I'd compare this to Western slavery where slaves were allowed to marry and have families, and how once the British ended slavery in their country and colonies, they used their navy, the largest in the world, to hunt down slave ships and end the slave trade worldwide.
I'd also teach them about indentured slavery, spirit gangs, and kid nabbing. I'd show them the math on how it was easier for plantation owners to buy kidnapped orphans and vagrants off servant boats rather than buy a slave. Indentured servants weren't laid until their lease was up, and those were typically 7 years. Most would either run away penniless or die before then. The most famous example is in Barbados where Oliver Cromwell sent all his Irish POWs. The island used to be nothing but paddies working on sugar plantations, but they all died of sunburn infections and being worked to death before their lease was up. Celtic songs are still sung by the current black slave descendants in Barbados, but there are no more Celts on the island.
Anyway, I'd teach about a few more things like how McCarthy was proved right by the Venona Papers, etc., but my biggest lesson I wanted them to walk away with is their ability to say no and explain why they disagree. Anyone in my class my allowed to take any position they wanted to in a debate. They could be a straight up commie, but as long as they argued properly and articulated their points and told me why they believe what they do, I never penalized them.
