Well, I can remember. It was 1806 and the French got the jitters. But it took another almost 30 years to abolish slavery. And what about the colonies? They are all independent or still ruled by the superior race? Every country got its own history. Some histories you'll better not remember: However, everybody remembers the German Holocaust if Gaza/Israel is mentioned.
It all happened and happens. No need for a statue glorifying the past. I mean Trafalgar.
