Around the turn of the 20th century, progressives laid out a plan to take over America. They knew they had several major obstacles that needed to be overcome and that it would take a slow gradual process about 100 years to accomplish the goal. One of the obstacles was Christianity. America was founded on Christian biblical principles, morals and values. A religious nation would not give up easily, unless that foundation was slowly eroded which has been done quite successfully.
A second major obstacle that needed to be overcome was the strong bonds of traditional families. The parental influence was very strong a century ago and most young people listened to what their parents said and taught. Today, divorce is rampant with many kids growing up in broken and fatherless homes. Schools are teaching kids to ignore their parental authority. Same-sex marriages helped to undermine the strong traditional family bonds.
