X marks the spot/X is known

Malcolm X was my favorite book we read this whole year. I am almost embarrassed to say that I had never read the Autobiography of Malcolm X before this year, I had only seen the Spike Lee movie. I learned alot about him during this unit, and it made me feel like he should be recognized more than he is. He viewed the world differently than a lot of people, but he is definitely responsible for the advancement of african americans during that time. We grew up knowing the date of Martin Luther King's assassination, and we have a holiday for his birthday, but until i read this book I knew neither about Malcolm X. I wonder why that is...
