Affiliate Marketing Secrets

“The fastest growing “religious” group in America is made up of people with no religion at all, according to a Pew survey showing that one in five Americans is not affiliated with any religion.
The number of these Americans has grown by 25% just in the past five years, according to a survey released Thursday by the Pew Forum on Religion and Public Life.”http://religion.blogs.cnn.com/2012/10/09…

I’m wondering if religions require indoctrination and complete trust on an unquestionable “god” and a book, how do those religiously-affiliated schools teach children that crucial critical thinking skill? Don’t intelligent parents find it pointless to let their kids brainwashed, even for a good cause?
