what was the difference between Abraham Lincoln's personal opinion if slavery and his professional intentions regarding slavery?

Concerning an issue on slavery, Lincoln looked a rather controversial figure. On the one hand, he advocated the abolition of slavery; on the other, he did not support the idea of social and political equality of the black and white races. " I am not, and have never been, a supporter of achieving the social and political equality of the white and black races. "I am not, and have never been, a supporter of black people, like voters or jurors, and allowing them to hold public office," said Lincoln. However, in his opinion, it is unthinkable when one person works hard and the other appropriates the fruits of his labor.
