By the way, I generally agree with Hanna's point about the importance of preserving local traditions and resisting a homogeneous global culture that's disproportionately Americanized.

However, one alternative argument for Hanna to think about is that the beloved Christmas tree or ёлочка was a purely localized Bavarian custom until the time of Martin Luther's Reformation. Luther began encouraging German-speaking Protestants outside of the Bavaria region to put up Christmas trees as an alternative to the traditional crèche (aka "Nativity scene"). He considered the Nativity scenes to be "too Roman Catholic", and more generally, a possible temptation to idol-worship because human figurines were used.

But even after Luther, the Christmas tree did not become popular outside of Germany until Queen Victoria began putting up decorated trees in honor of Prince Albert's Bavarian origins. Of course, once the royal court started doing it, Christmas trees almost instantly became fashionable in British high society, both among the aristocracy and among wealthy commoners.

From there, the custom was adopted by royalty and aristocracy in other parts of Europe (including the Romanovs in Russia), and also by "blue-blooded" American millionaires of the Victorian age, who loved to imitate the British aristocracy. And eventually, the Christmas tree tradition spread downward through the middle classes in many Christian countries.

(And nowadays, in spite of the "anti-Papist" intentions of Martin Luther, Christmas trees are certainly universal among Roman Catholics in the Anglo-American world, while Nativity scenes are widely popular among Protestants -- including Lutherans!)

So, if you complain about Coca-Cola and McDonald's as "cultural imperialism", but you put up a ёлочка in your home, you're not being totally consistent from a historical point of view.
