No one likes to be marginalized. But if you follow Christ in this post-modern culture, you will be. Tom Gilson, author of the book, "Critical Conversations: A Christian Parents' Guide to Discussing Homosexuality with Teens," reminds us that there's an incessant onslaught against God and against truth today. Moms and dads need to have critical conversations with their kids about spiritual and cultural issues so they will know how to respond when questioned about their faith and values.
