According to Douglass,what should the Fourth of July mean to white people? from narrative of the life of frederick douglass

Douglass
uses the Fourth of July to bring to
light how far America has to go in ensuring that its
promises are delivered
to all of its citizens.  The mere mention of "Independence Day"
rings hollow
to Douglass when the same nation condones or refuses to abolish the institution
of
slavery.  For Douglass, Independence Day offers the best opportunity to
explore the chasm
between America's promises and its realities.  The promises
of freedom for wealthy, white
Americans have to be contrasted with the
reality of oppression and bondage for its darker
skinned inhabitants. 
Douglass believes that White Americans have to grasp the fact that as
slavery
exists, American political hopes ring hollow and its foundational beliefs have to
be
questioned.
