He covered that by the earlier line in the story:
"...descendants call the bloody fighting that followed between Acadians and the Yankee troops sent to carry out the British orders.
Good point. But what about southerners? I hear they dont like to be refered to as Yankees...hahahaha
I think its a little dishonest to imply that it was the Americans and the British who did this. It was the British gov't that ordered the expulsion of the Acadians. It was the King's men in N.America who did it. The author is an idiot.
