I don't see how this is caring. This is dismissing and invalidating the work of large class of people (Westerners and English-speaking people) by applying a jargon label "imperialist" (what does that even mean here? That they are about to don pith helmets and rush out to re-conquer India?) and implying that this label automatically makes their contributions less worthy - to which implication you just added the implication that they are presumed to be incapable of caring about other people. Does look like particularly helpful for anything, rather quite alienating.
