[harry potter] why is voldemort more feared than Grindelwald?

Voldemort terrorized only England, while Grindelwald terrorized the whole of Europe (practically the whole world) there is no comparison with a single country with several countries.

Because Harry Potter is set in England.

It's very possible that in the USA no-one gives a shit (indeed, if Voldemort is seen as a local problem, it explains why no-one stepped in to help), but the books are set in a place where its still fresh in everyone's memory that he started a brutal civil war and nearly set up a genocidal regime. Of course they're going to be more scared of him then a historical figure from decades ago.
