It's just like the global warming issue. If we were to do everything they want us to do to "stop" it and it still got warmer, they would say it just proves we need to do even more. If it somehow does get cooler, then they would say they were right even if they can't prove what was done had anything to do with the cooling.
Socialist thinking is dangerous, especially when applied to children in public schools. It affects the collective mind to the point that I wonder if freedom can survive.
The reason that Socialism is so dangerous is because there is no such thing as a "collective mind" - there are only individual minds and consciousnesses whose duty it is to make decisions that define the quality of the lives that they control. Socialism denies the validity of individual perception and decision-making ability, and substitutes for personal choice the powers of the all-knowing State.
God gave us our own minds and how we choose to use them is up to us. When others insist that they know better than we how to choose - we need to fight back, because when we do not object, our freedoms vanish like dew on the warm grass.
