Answer:
The claim that Douglass is making in his speech is to abolish slave trade or the practice of slavery in the United States.
Explanation:
Frederick Douglass was an abolitionist, writer, orator and an American social reformer. His birth date is uncertain. He was born into slavery in Maryland. His mother was an African while his father was a white-man.
On July 5, 1852, Douglass gave a speech referring to the American Independence celebrations of 4th July.
On 4th July 1776, America became a free nation from the rules and oppression of the Great Britain.
He delivered this speech 'What to the American slave is your Fourth July?' in Corinthian hall, to Anti-slavery society. In his speech, Douglass is making comparison between the lives of American Slaves under the Britishers to that of the slaves in the United States.
Douglass in the given excerpt is saying that this day of independence of America is nothing more than a 'gross injustice' to the slaves living in the United States. United States Declaration of Independence states the rights and equality of all men as they are all created equal by God.
The point that he wants to make in his speech is that just like Americans fought for their liberty from Britishers, they should fight that same fight for the slaves of the United States. In short, slave trade should be abolished from America because they know what it means to be slave themselves.
