Quote of the Week
The denial or distortion of history is an assault on truth and understanding. Comprehension and memory of the past are crucial to how we understand ourselves, our society, and our goals for the future. Intentionally denying or distorting the historical record threatens communal understanding of how to safeguard democracy and individual rights.
