This thread discusses the Content article: On Lovecraft and Racism

It seems that the author's premise was that HPL was a racist in his own right. I believe that HPL's racism was more a function of his acculturation in 1920's white, Anglo-Saxon protestantism; a cultural "norm," if you will, for his time and place, and not necessarily a personally held item of philosophy.

Then too, HPL was attempting to write and publish in "pulp" magazine system that was one of the organs perpetuating those racial (and sexual) stereotypes of the time. Even had he held significantly different personal beliefs, he probably would have had to write things like the quotes selected by the author, simply in order to be published at the time.

While I don't disagree that HPL was a "racist" by our current definition of the word; by the norms of his time, he was merely expressing the cultural values of his society. To pillory him for that seems a trifle unfair given his inability to defend himself from what is, after all, a somewhat gratuitous critique.
