Watson used his credibility to advance unscientific eugenics theories for years. The impropriety suggested by the circumstances surrounding the discovery of the structure of DNA serves to undermine the arguments of people who are liable to think, "Well, he was smart enough to make one of the most important scientific discoveries of all time, how could he get race theory wrong?".

Watson's shadow would not extend so far if Franklin's role were known - not just because it would have diminished his, but also because her presence would have undermined attitudes that marginalized non-white-men, in the field of science and beyond. It matters a great deal, unfortunately. And it's a tough pill to swallow for a lot of people who have their pride wrapped up in what he represents.
