You can’t build up immunity to a disease by never experiencing it.
I hear a lot of people around these parts vowing to homeschool their kids because of this that or the other public schools are doing–usually something related to modern liberal politics. They’re afraid of their kids learning about gay marriage, or social justice, or something similar, so they decide that the solution is just to keep the kids at home where they can learn without the agenda.
Now, to be clear, I have nothing against homeschooling–all of the evidence and studies I’ve seen on the subject indicate that it is a perfectly fine way to educate a kid, so long as the parents are mentally healthy, not-abusive, etc. If you happen to live in an area where there aren’t a lot of other people around, then you might want to consider conventional schools just because your neighborhood makes it difficult to associate with other humans, but otherwise, I see homeschooling as just another method of educating a kid. If your goal is merely to provide your kid with the best education possible, this post is not for you.
However, if your goal in homeschooling is to prevent your kid from learning about broad social trends, political ideologies, or ideas you don’t like, anecdotal evidence suggests you will fail.
Your kid will grow up, they will leave the house, and then they will learn about all of the stuff everyone else believes. If everyone out there believes X, and your kid is even remotely neurologically normal, then your kid will learn about X and start believing it.
Remember, the vast majority of normal people pick up their ideas and beliefs from the other people around them. This is not a bug. This is a very important ability. Other people are treasure troves of useful information about how to stay alive and not die. Imitating others is how you learned to talk, which things are good to eat, and how to behave in new situations. If you’re standing near a road with your friend, and they suddenly jump back, it’s in your interest to jump back, too.
Inability to properly imitate others is extremely problematic and one of the basic symptoms of autism.
So, like I said, if your kids are remotely normal, they will pick up the values of the dominant culture upon exposure. And then they will decide that you were a looney nutcase.
I’m going to talk about the personal experiences of 5 people I know who were homeschooled by conservative Christians. I’m not cherry-picking; they are all the homeschooled people I know.
One went to Bible college, got pregnant, dropped out, and got married. This person still professes Christian faith, but believes far more in materialism.
The second dropped out of college, became a die-hard SJW, and changed genders. I doubt they are still Christian, and they regard their parents’ faith as a cult.
Third completed college, but has become a die-hard SJW. Has a very dim view of conservative Christianity. No children.
Fourth became an atheist liberal who believes in gay marriage and abortion.
Fifth became a die-hard SJW who hates conservative Christianity, thinks their parents were culty, and makes pornography.
If you want an in-depth look at how this happens, I recommend the webcomic Dumbing of Age.
In all of these cases, the parents homeschooled to keep their kids isolated from certain ideas, ideologies, or behaviors. The kids graduated with very little experience of the world. They did not have a thorough understanding of how the world works, the philosophies out there, and why, exactly, their parents disagreed.
As a result, when exposed to the meme-viruses of the world, they get infected. They have no defenses.
In my experience, the vast majority of conservatives cannot articulate a coherent explanation for their beliefs, and do not attempt to explain their underlying reasoning to their kids. Many of them, I suspect, simply believe as they do because of habit, convenience, or because everyone else in their area does. Liberalism, by contrast, has put a lot of effort into making arguments against conservative beliefs.
For example, let’s take gay marriage. Common conservative arguments against gay marriage are “Ew! Gay people are gross!” “God says homosexuality is a sin,” and “The purpose of marriage is to make children.”
Liberals have all sorts of counter-arguments, like, “Ellen DeGeneres isn’t icky,” “Separation of Church and State,” and “But we let infertile people get married.”
In short, if it is really important to you that your kid think gay marriage is a bad idea, you’d better have a better, more coherent argument than that. Same for everything else in your memeplex/ideology/worldview–up to and including the existence of god. You might think your proof for the existence of god is pretty solid, but most of the people your kids will be associating with will probably think rather little of your proofs.
If you can’t explain your ideology and rigorously support it, showing your kids that your explanations of how the world works is better than the dominant ones, then you’d be better off just letting your kid go to public school and then doing your best to defend any objections to the curriculum when they come up. Your kids might think you’re kind of weird (just as I thought my parents were kind of weird in the early 90s for defending the use of aerosols/CFCs and not being concerned about the hole in the ozone layer), but they won’t hate you or think you’re a loon.
