She is not personally, directly responsible for Britain's colonialism,
but in all likelihood (if you look at how the American and Indian
economies are intertwined) she does benefit from it. I know I benefit
from it. Whether and how that translates to responsibility is a matter
on which many people disagree. I think that in this case she does have
some responsibility.

(This is not to disagree that ownership of epics is thorny in this case
and others.)
