Why have a holiday celebrating the end of slavery? It didn't' end there. Becuase of John Wilkes booth murdering Abe Lincoln abolitionist Frederick Douglass could not encourage a stronger integration ,especially in the south . When the next president came there was lynching segregation, Neo slavery.This would end under martin Luther King's technique.The post version of this technique is in effective .Jimmy carter followed by Bill and hillray Clinton messed it up.As a result it not effective any more Because of this I won't celebrate June teenth.
