Yeah, I think that's absolutely true and fair. It's possible that Lady R might have been a truly awesome scientist in a different world, and it's a good idea to remember all those "flowers born to blush unseen". And, in any case, maybe Lady R is just a really interesting person! You don't have to be a (drumroll) Great Scientist to be an interesting biography subject. My objection is to overestimating someone's actual achievements in the interests of a political agenda, no matter how well-meaning.
