It's been building. It was funny when they said that Beethoven was black. It was funny when they said Africans built stonehenge... now they are just saying everything was non European in Europe. The people of "follow the science" sure don't care about historical facts.
How can anyone see this as anything than what it is? Trying to replace white culture and its history.
What they won't admit though is that the cultures they are bringing in never developed an auto industry, an aircraft industry, tech industries, literature, art and music, engineering.... All that goes away when they get the majority because it's all about allah.
