I know my history and that they didn't just go out and attack the British, but the point is war and killing does not mean you don't think all men are equal endowed with certain inalienable rights.
Same with the wars in the Bible. There is a reason, right or wrong, that God says to wipe out certain nations. It's not because they are not equal but because they are equal as men and therefore responsible for their sins.
Being equal in this sense does not mean one nation or group cannot be more favored. It's talking about equal before the law within a nation.
