It shouldn't. When Americans first arrived in America, they had nothing. The Indians on the island sympathized with them, sent them necessities of life, and specially sent people to teach them how to hunt, fish and grow corn and pumpkins. Finally, the immigrants got a bumper harvest. During the celebration, according to religious traditions and customs, they set a day to thank God and invited Indians to spend the festival with them to thank them. On Thanksgiving Day, they went to church, held bonfires and held a series of activities as usual. Then these activities have been handed down and become the modern Thanksgiving Day. Children's shoes are usually finished when they see this. But what's the next story? ? Children's shoes who have studied history before all know that the arrival of immigrants has brought disastrous destruction to Indians throughout America. They brought with them diseases that did not exist on the American continent-smallpox, measles, typhus, yellow fever and so on, which caused Indians to die at a harmful rate. In addition, the immigrants brought ambitious European invaders, whose advanced military technology conquered the whole America and brought destruction to the whole Indian race. For this reason, Indian aborigines call Thanksgiving Day "National National Cleansing Day", "National Genocide Day" or "National Day of Silence".
