Read the following excerpt from a speech delivered by a historian at a commemorative event:
"As we gather here to honor the legacy of those who fought for our freedom, we must remember that their struggles were not in vain. They challenged the status quo, shattered societal shackles, and illuminated the paths of justice. Our present obligation is to uphold their sacrifices through vigilant activism, championing equality for all citizens regardless of race, creed, or gender. This fight continues today as we face new challenges that threaten the principles they held so dearly. Let us stand united, recalling our history not only to celebrate our gains but to ignite the fervor for justice that lies within each of us."
