I have read that Harriet Beecher Stowe's work (published 1852) is not encouraged by the educational establishment in the US because of the stereotypes it presents of black people as ill-educated and subservient.
However the case for it, given the position it occupies as arguably the most influential fictional text in US literature, and its historical importance, seems to me to be overwhelming. It demonstrates beyond doubt that slavery and Christianity cannot possibly co-exist - providing a monumental dichotomy to the society and politics of mid-nineteenth-century America.
What are the precise nature of the arguments against it being taught educationally (it is a classic) and is the work universally discouraged among teachers and educators?
