According to Frederick Douglass, what is even worse than the internal slave trade?from narrative of the life of the frederick douglass book

Frederick Douglass's thoughts about the internal slave
trade are not found in the book you mention.  They are found in a speech he gave on the
Fourth of July, 1852 in Rochester, New York.

In that
speech, he says that the thing that is even worse than the internal slave trade is the
Fugitive Slave Act of 1850.  That law made it very easy for any black person in the
North (whether an escaped slave or not) to be taken and sent into slavery.  Douglass
says this law makes the whole of the country a slave country by forcing the Northern
states to help send slaves back into slavery.
