I only have time for a quick answer...
No, I'm not speaking of keeping them home full time, just about common sense.
Sin is out there, most certainly, but the city school system where I live is alive and pulsating with things children should NOT have to be exposed to.
My kids will see this stuff in the world, but school is where they are sent to LEARN about life. The schools are teaching sin as good and often mocking good.
This is NOT the type of exposure children need to grow and thrive.
I don't need to bring sin to my children, they are surrounded by it. I do not take my children to truck stops at night to teach them how to deal with prostitutions, I do not move to a part of town fraught with drug dealers to teach them how to cope with drugs, but you are saying I shouldn't be concerned with putting them in a public school where they are taught aberrant sexual behavior?
Should I be especially repulsed by this topic and focus on it more than, say, smoking? I am and I do because this it is more physically and spiritually damaging.
No, kids shouldn't be afraid to talk to their parents but trust me, many are. I had one father tell me "I don't even want to know" when talking about his daughter and what happens in school. He is being willfully ignorant because he doesn't want to deal with it. His daughter will NOT be going to him with questions and he is not aware that she even has them.
There ARE many parents like that...if the kid even QUESTIONS these things, the parent gets angry and treats them stupid instead of using the Bible and logic and teaching the kid how to think for him/herself. Sometimes the kid is simply too embarrassed.
Whatever the case, homeschooling is done for many different reasons.
I believe exposure to this behavior on a daily basis for a child is spiritually harmful and a VERY valid reason to add to "reasons to homeschool."
It is a warning to those that are considering the pros and cons of public vs home and an encouragement for those that ARE homeschooling.
If you don't agree, so be it. I have older teens, younger teens, and tweens. I homeschooled, I used private schools, and I used public schools. I have first-hand knowledge of all three and first-hand experience in the public schools.
If it isn't a problem for you now, good. That's nice. Don't toss it out though, remember it when your kids are a little older and you're no longer their hero who knows everything.
Maybe you'll be lucky and have NONE of your kids question it. That would be nice too. I have five, out of five, one is questioning it. I never thought she would, and she is.
Thankfully she talks to me. I'm lucky.
It's not an argument, it's a statement and a warning. If you don't agree with it there's not much I can do but say "hey, watch for it anyhow and try to make sure your kids feel safe and okay with talking to you if they end up with questions or disagreements."
I gotta go...Wish me luck, I took off work with pay to...well, go work without pay. (yeah, I'm a public school graduate)
