Answer:
Racism.
Explanation:
The fight against racism in American society is still prevalent. History witnessed the struggle of the African Americans who have received the legislative reforms from time to time to enhance their greater participation but continued to fight an equal status to their white counterparts.
Though slavery was abolished voting rights were secured in the nineteenth century, there was still discrimination against the black people who resist their social and economic mobility. Civil rights laws of the 1950's and 1960's enhance their participation in public life but racial attacks were still prevalent throughout the 20th century.
