I mean, in my lifetime alone, America has killed literally millions of people who offered it no harm at all.

Consider all the people who died in the Vietnam War, not one of who had offered any American any harm before they were invaded, based on the "Domino Theory".

We now know for certain that the Domino Theory was paranoid delusion, because Vietnam fell, and Asia did not fall into communism.

But not only has America refused to pay any reparations to Vietnam, they have insisted that Vietnam pay the United States back for the war on their own country!

The US also carpet bombed Laos and Cambodia, countries that were never at war with the US, because they wrongly thought that this would give them some sort of strategic advantage. This is a war crime by anyone's definition, but the monster who planned this lived a long life of luxury and "honor"

And America has gone on to commit the same slaughter again and again, in Central and South America and most recently in Iraq.

America pretends to be a Christian country, but it gleefully kill people in other countries by the millions.

It's perfectly reasonable to find mass murder morally repugnant. Your using the word "rant" is unjustified and puts you in an unpleasant moral position.
