Invest that energy demanding clean water in Michigan and reparations for black slavery since you care so much for humanity. But you won't because it brings guilt about your own history. As for "i can tackle both issues", common sense says that Americans are more likely to affect their own policies in a democratic country where they elect their leaders than in far distant lands.

You bringing a "a better world" is dangerous, as we have seen in Iraq and Libya. This Kipling's call for a better world in far distant lands is quite old and a disguise for imperialist projects. Even if you are sincere, the hate is used to justify wars against those leaders "who abuse their own people".
