Short swipe:

"I’d make the case that Lovecraft’s fiction–and Lovecraftian horror–depends on the xenophobia that was endemic to
Lovecraft’s work to the point that without it, many his stories lose their unique and uniquely profound effect.

“The Horror in Red Hook” is a direct channeling of Lovecraft’s loathing of newcomers to New York City; the
real horror of “The Call of Cthulhu” is not the octopus-headed demigod that emerges out of his underwater city to
kill all the people, but the people themselves–all either eugenically unfit denizens of the bayou or “primitive”
island cultures whose religious practices amount to a kind of proactive nihilism.

The manifestation of Nyarlathotep in the eponymous story is that of a black man
bearing trinkets, who seduces the good white folk of America into authoring their own demise.

There are other things going on in Lovecraft too: there’s the bestiary/pantheon of fantastically alien gods and
monsters; that overheated prose that veers so easily between the sublime and the leaden; his fearful, bookish characters.

But those are characteristics, aesthetics; not fundamentals. They are not the agenda.

The agenda in Lovecraft’s fiction is clear, and woven deep into the bones of his stories."
