Final answer:
The tragic aspect of the Emancipation Proclamation, according to Dr. King, is that it did not immediately free all slaves, and it fell short in achieving full liberation. This discrepancy between the promise of freedom and its limited implementation became a catalyst for the ongoing fight for civil rights in America.
Step-by-step explanation:
According to Dr. King, the tragic aspect of the Emancipation Proclamation is that although it proclaimed freedom for enslaved people, it did not immediately free all slaves in both the North and South, but only those in the Confederate states still in rebellion against the Union. Dr. King makes the connection that while the Emancipation Proclamation marked a significant step forward in the abolition of slavery, it fell short in achieving full liberation for all enslaved people. He highlights the discrepancy between the promise of freedom and its limited implementation, which served as a catalyst for the ongoing fight for civil rights in America.
