well, if you're not an especially bright kid in high school history class learning about the holocaust and you happen to type "did the holocaust" then the autocomplete can be a nice little introduction to the world of fascism.

Maybe you are actually looking for did the holocaust happen or some such because the skinhead in your class said the holocaust didn't really happen. And then Google shows you the first search result that asserts the holocaust didn't happen, not the first search result that tells you about holocaust denialism.

So sure some people are looking for stormfront but maybe some people are also just looking, and unlucky enough to use google for their search.
