Christian parents should not assume their kids are equipped to filter out the false claims they will likely encounter. Christianity is the opposite of how it is often portrayed in our culture and is none of those negative things indicated above. You owe it to yourselves and your kids to anticipate the attacks and think through how they can be countered. Don't assume your excellent child rearing will be enough. We must stand up to the challenge and test our own faith, if necessary, reviewing what and why we believe. If we can't explain it, should we expect our kids to understand it?
Please don't dismiss these warnings as my opportunistic construction of a straw man. As my friend Frank Turek warns, "Christian young people are leaving the church at an alarming rate, mainly because they are not equipped to examine the skepticism and atheism they encounter, often coming from their college professors, after leaving home." So do your homework and help arm your kids. Or consult other sources for help, such as Frank's website, CrossExamined.org, which has information on how you can help teach or reinforce in your kids why Christianity is true and reasonable -- and loving.
Likewise, as politically conservative parents, you should help insulate your kids from the propaganda coming their way. You might want to first remind them that a strong majority of Americans are center-right and reject most of the ideas being forced on us by the vocal, strident and extreme leftist minority in this country. Next, of course, you need to address the specific libels hurled at conservatives and substantively respond to and refute the claims that they are bigoted, selfish and unreasonable.
If you have time to address little else, at least strive to explain to your kids in a thoughtful way why conservatism is not only not uncompassionate but also more compassionate, open-minded, tolerant, science-compatible and consistent with our human experiences than liberalism. You must do what you can to help prevent your kids from being shamed into liberalism through its false claim of having a monopoly on compassion.
Parents, are you prepared? Are your kids? Can we agree we have some work to do?
