Yeah, once this got out to the news, it was pretty much guaranteed that this memo was the first thing anyone would know about this guy. I agree that's not "fair" in an objective sense -- everyone should get to learn from their mistakes, especially if they were made in a "safe" space where feedback was encouraged.
That's why I'm very curious exactly how this got distributed early on. Did someone take private feedback and socialize it?
Or was feedback always a public bulletin board, where there's some shared responsibility on both readers and writers to think about the context? Or did Damore socialize it independently to prove support for his ideas?
If feedback was private, I think HR could take a firm line about what policies and principles Damore needs to adopt (at least at the workplace) to participate in his employment community, without helping his name get published with this memo (and possibly even without firing him). But the moment it got published changed the stakes for everyone involved, and not just due to PR. It's fair to ask: "can I require my female and minority employees to work with someone who has asserted that biological differences make them less likely to succeed?"
As far as the media goes, they've done what they're paid to do and socialize the most extreme opinions (most rejecting but some supporting Damore). I think that sucks for society but is a much bigger problem than this case.
