So you agree to a bunch of examples of terrible things she's done, and then counterbalance it with a vague "she's done a lot of good for the community over the past 20 years"?
Oh, and she was considerate towards your feelings in an email, and a followup email?
I too have seen many corporate higher-ups be highly pleasant when you talk/correspond with them. But they do jack shit about the actual issue, but assure you that they care about your feelings.
I'd rather she was an absolute bitch to everyone, but actually steered the organization in the right direction. That would have had a better positive impact on the world than a few placating emails.
