We have a winner. Man sometimes logical fallacies on these threads is appalling. Considering blacks to be inferior and opposing slavery are not mutually exclusive. You can oppose slavery and still consider blacks inferior or vice versa. You could think blacks were equal and STILL support slavery.
Your last sentence could NEVER be true!! One could NEVER think a group is equal to another yet think it would be ok to ENSLAVE them! Ridiculous...you might want to re-think it.
