The opinions which Lovecraft expressed regarding race and religion, especially in his early writing, are no longer considered to be socially acceptable. Some modern readers have criticised the themes of racism in some of Lovecraft's stories. Particularly of note are the two pieces, The Horror at Red Hook and The Street, in which he describes the immigrants of his day as decadent and potentially dangerous. Some of his stories, such as The Shadow over Innsmouth and Facts Concerning the Late Arthur Jermyn and His Family, might warn against the dangers of miscegenation. Still others, such as Herbert West: Reanimator, contain overtly racist depictions of non-white races and the immigrant population.
Lovecraft's personal correspondence indicates that he did indeed hold racist beliefs. This, however, was regarded as an impolite but probable scientific fact within the anglo-rationalist intellectual framework of the time.
