Mjollnir,
I don't know that it's so much a matter of not liking the themes of Lovecraftian Horror, as addressing the unfortunate stereotypes prevalent in much of adventure fiction in the late 19th and early 20th century and determining how to address those stereotypes in a social setting like a game, where others might be offended.
Whether discussing Kipling, Haggard, Howard or Lovecraft, or any number of writers, the trope of the "civilized" Anglo Saxon versus the inscrutable, mysterious, dangerous, and feral "native" has not aged well. This is not to say that these books and short stories should not be read and enjoyed. Quite the contrary. I like reading Lovecraft and Howard. I just happen not to share their sentiments on certain subjects.
Bebs is making a reasonable request, asking for suggestions about DBTH, to mitigate some of its more offensive elements. I think there's a lot that can be enjoyed in the scenario, and mechanically it's a good way of introducing new Keepers and Players to the game, but I personally would not run it as is. It's up to the Keeper to gauge his or her own group and adjust the game so that it's fun for them.
