An ethical person - like a politician, banker or lawyer - may know right from wrong, but unlike a politician, a moral person lives it.
A Confederate soldier who obviously didn't own any slaves,when asked by a group of Yankee soldiers why he was fighting, the Rebel replied, "I'm fighting because you're down here." Do you think an Iraqi, Afghani, Syrian, Libyan, Pakistani, etc. would answer similarly today? Homeland is always homeland.
