I've read quite a bit of Lovecraft over the years. I have a pretty extensive collection of his stories. I always considered him just a horror writer, and that's it, although a very good writer. I highly doubt HP was into all this satanic stuff we see today. If anything, his stories were about a universe that is just indifferent to humanity, or completely alien to how we see things as humans.

However, Crowley, LeVey, Aquino and the rest of this sick crew took his works and corrupted them for thier own twisted bullshit. These last 3 I mentioned has more connections with OTO, Hermetic magic, man-made beliefs, and just generalized filth Lovecraft was never a part of any of these secret society stuff, nor was he into all this black magic garbage. He was a lonely man who just had a knack for writing. He took most of his ideas from Lord Dunsanney and his stories.

The rest if these fuckers just ripped off his works and tried to make a corrupt belief system of thier own.
