Cultural bolshevism is a term used to describe a political ideology that was popular in Russia in the early 20th century. This ideology was based on the idea that cultural values and traditions were holding back progress, and that a new, more revolutionary culture was needed in order to create a more equal and just society.
To explain it like you are five, imagine you have a toy that you really like to play with, but your parents tell you that it's time to give it to your little brother or sister. You might feel sad or upset, but your parents explain to you that it's important to share and be fair. This is kind of like cultural bolshevism, because it believes that old traditions and values need to be shared or changed in order to make the world a more fair and equal place.
However, not everyone agreed with this idea. Some people thought that it was important to keep traditional values and culture, because it was a part of their identity and history. They believed that creating a new culture would be like throwing away their past and losing their sense of self.
So, cultural bolshevism was a controversial idea that caused a lot of debate and conflict in Russia. Eventually, it became a powerful force in the rise of communism, which swept across Russia and many other countries in the 20th century.
