I am with you on this one. I do think it would be appropriate to have a disclaimer in the beginning, saying that these words used to have a different meaning, and that in the context of the time they were written they meant different things than today.
There is a German book where this is done that uses the N word for people of color.
This is the more appropriate way of handling this, because i am totally with you: we shouldn’t change what was written in books. If we start doing that, we destroy what authors have done, and in a sense we also edit history, because in this case we try to erase that these words were used in another context back in the days.

If it’s not baked that actually sounds delicious.
