But anyway, linking Nelson the debate in the US is tenuous at best. Lee and Nelson were both products of their time, and both had unsavoury views to modern eyes, but Lee, unlike Nelson, represented divisions within the country; Nelson, I think, was admired rather more universally (in Britain, at least; as another illustration that context matters to statues, I do hope that no-one here would suggest putting a statue of Nelson up in the Place de la Concorde). And, of course, Robert Lee himself suggested that such divisions should be "consigned to oblivion", rather than re-opened due to war memorials and statues, etc.
It's a shame, because there are probably a great many people who are a little too proud of British history without really looking at the parts they should be less proud of. If the original article had stuck to that, it might have made a good point. As it is, that's lost in the noise.
