As @Jay has said, the example the OP has been given xxx doesn't change anything about racism, he just gives an opinion of it. So despite what the OP has been asked for, the process is not of changing a thing from bad to good, but a process of presenting a view of something which conflicts with the popular, but not universal, opinion of it.

In that light I would suggest the verb 'To Recast', defined in the OED (Sign in required) as

To give (a person, occupation, etc.) a new or different role or image; to reinvent or re-present as something different.
