Hence, I'd like to take this opportunity to appeal for a charitable reading of posts of this nature

Duly noted, thanks. This kind of tone deafness seems to be a pattern here in the LW-sphere, however. For instance, look at this:

If funding were available, the Centre for Effective Altruism would consider hiring someone to work closely with Prof Nick Bostrom to provide anything and everything he needs to be more productive.

Really?

An appeal to charity in the reading of "public-facing, external communication" is a little odd. Public-facing means you can't beg off on social incompetence, being overworked, etc. You have to convince the public of something, and they don't owe you charity in how they read your message. They will retreat to their prejudices and gut instincts right away. It is in the job description of public-facing communication to deal with this.
