Hatred to slavery is very generally little more than hatred of negroes

We write in the cause of Truth and Humanity, and will not play the advocate for master or for slave.

The aversion to negroes, the antipathy of race, is much greater at the North than at the South; and it is very probable that this antipathy to the person of the negro, is confounded with or generates hatred of the institution with which he is usually connected. Hatred to slavery is very generally little more than hatred of negroes.
~ George Fitzhugh (1857)
