Ah, yes, but it implies that the USA thought of ending slavery first, doesn't it? Remember what a shock America got in the late 50's when Sputnik went up and Americans were forced to admit, for once, in no uncertain terms, that SOMEBODY ELSE had done something FIRST!!! (AAAARGH!)

It was almost hara-kiri time in fortress America.

Well, too bad. The British ended slavery first. And they didn't have to fight a five year war and destroy half the country doing it to accomplish that, either. They just discussed it and took a vote in parliament, and it was done.

Runaway slaves used to come to Canada for sanctuary, remember? Just like runaway progressives do now...

Sitting Bull's Lakota Sioux came to Canada for sanctuary too, after Little Big Horn. It seems to be a trend. (they had to eventually return, because there wasn't enough game left to keep them alive on the Canadian prairies).
