Lovecraft's "personal views" (i. e. racism) seeped into his works on numerous occasions. Just read his books and see how often he references lowly, ugly and dumb foreigners as minions of some big bad guy or half-breeds. He had a big thing for racial purity among humans (so mixed race individuals are usually portrayed as particularly sickening, again usually as the barely human minions of some big bad guy), which also informed some of his other stories about human hybridization with Deep Ones. I still like a lot of what he wrote (not all of it by far, though; there are lots of garbage there as well, among the gems), but it's really problematic to downplay these tendencies rather than acknowledge and criticize them. A lot of people who did or made great things were awful in any number of ways. Don't let their accomplishments blind you to their flaws, don't elevate them onto an altar, don't worship them as heroes but understand them in their entirety, warts and all.
