Please cite just one example on FR of the acceptability or tolerance of slavery. Just one.
Now, do you agree with me that this is acceptance of slavery? I personally think this is not only acceptance, but borders on endorsement, particularly taking into account that the slave system was becoming increasingly more, not less, repressive in the 1850's.
If you don't agree, then we can have that discussion right here in this thread.
If you do agree, then I can find those threads, but knowing the FR search system, don't expect it to happen within the next few hours.
