'Anyone can give them answers. They'll get plenty of answers in school. And they'll be tested on them in school. What we give them is an environment where they can question safely.'
That came out of a conversation between the guys at Penny Arcade about talking to your kids about religion.
I would imagine this advice isn't limited to religion alone. All kinds of people have all kinds of ideas. Some of them are good, and some of them are bad, and most people (including us) aren't hesitant to share their ideas with our kids.
A long time ago I realized that the people who go around 'telling it like it is' are often the most full of shit*. If I can teach my kids how to wade through the shit to get to the good stuff--and how to recognize good stuff when they get to it--I think I'll have done a pretty decent job in a key area of parenting. If I can teach them how to wade through my shit as well, I'll have gone above and beyond.
* as someone who spends a lot of time sharing his opinions with folks, maybe I should meditate on that a little bit.
