My best advice to you is to do practical deschooling with your kids after school hours. Get them to share what they have learned, especially with regards to history and politics and deconstruct the liberal ideological trash while bringing in historical facts and countervailing political perspectives.

Also take the time to get your kid involved in learning about different cultures. If you're in certain parts of the US, take them to powwows for example. Actually get them to meet with indigenous people, as well as other marginalised groups, so they can develop an appreciation for humanity so that it can serve as a buffer to racism and bigotry. If your kid goes to a powwow on Sunday and then on Monday their teacher tells them "The native Americans used to live here in this very state!", playing that end of history bullshit liberal sleight of hand then your kids are gonna be like "Uh, nope. They're still here - I saw a bunch of them yesterday and you don't know wtf you're talking about." which is going to spare you a lot of effort in cognitively deconstructing the liberal narratives they get fed.

Follow @hungryrye on social media and see what they have to say about raising kids as leftists. There's gotta be more content creators out there doing this who you'd be able to draw inspiration from too.
