The writing I saw attributed to Erika Christakis was thoughtful, constructive, and polite. It didn't attack anybody, but promoted a viewpoint that talked about inclusion and the difficultly that can be experienced when attempting to understand the viewpoints of other groups. It's not at all combative.
I guess it just seems plainly self-evident to me that sensible discussion would be far more constructive towards solving the issues at hand. Harassment achieves almost nothing.
