Lovecraft was considered extremely racist in his day's standards too though.
First page, folks.
This is a pretty bonkers take given that Lovecraft predated the Holocaust and such. I feel like this is some idea people hear and then just regurgitate without really thinking about it.
Lovecraft's views were, by and large, very common during his lifetime. What is different is that we have a very extensive record of Lovecraft's views, which we do not have for the average individual from 1890-1937. Any examination of contemporary news accounts of the Scottsboro Boys Trial or the Massie Case will reveal beliefs in line with Lovecraft's, the same can be said for major newspaper accounts of the Nazis and Dunning School textbooks on the Civil War, slavery, and "horrors of Reconstruction." In terms of the material published in Weird Tales during his lifetime, Lovecraft's use of race is relatively unremarkable.
That does not mean Lovecraft was not racist, but in terms of his environment his racism is more shocking to us today because we do not normally encounter racial thought of that period, in fiction or otherwise.
