Thanksgiving celebrates white colonialism, and by extension, the murder of millions of innocent people. Between 1500 and 1900, North America's indigenous population decreased by an estimated 95%. Contrary to popular belief, only a tiny fraction of these deaths were via direct violence; the vast majority were caused by Old World diseases such as influenza, smallpox, and tuberculosis.
Racism has no rightful place on the planet. Due to its racist origins, Thanksgiving should be permanently abolished. The Canadian Charter of Rights and Freedoms provides for freedom from discrimination on a wide range of grounds, including ethnicity. Therefore, it is genuinely amazing that the holiday has yet to be ruled unconstitutional.
