Cultural war is tricky business. As a living entity, culture needs mechanisms of protection from external threats. But intellectual defensive systems can become an obstacle for evolution especially when a culture has fallen in love with itself to the point where criticism is no longer seen as a mechanism for progress. For all its merits, Western culture is affected by a plague of intellectual rigidity.
There is no need to generalize. There are many Westerners who are quite open to change and new ideas, perhaps more-so than any other major culture on Earth. This is only sufficient if these people can trigger an evolutionary step forwards by reaching a critical mass enough to spread a wave of change throughout society.
What does all this have to do with Christmas? It’s quite simple really. Changing the way we interpret Christmas is probably a litmus test for cultural evolution. Why do we need to reinterpret this cultural event? Because it is the avatar of a way of doing business that may have made sense in the 20th century, but will only lead to worsening the quality of life on this planet for future generations of human beings.
