> Good thing the original memo author has a PhD in biology then.

Your appeal to authority is pretty transparent... While the original memo author's work with various strains of yeast is indeed interesting, I'm not sure how it's relevant to the topic at hand...

An argument should stand on its own merits, not on a piece of paper on the author's wall.

His PhD is in "Systems Biology", isn't it? Which is more about computational approaches to understanding biological systems than, at the risk of simplifying horribly, "messy" biology.

> making people feel bad at their job is inappropriate (even though the memo did no such thing)

Say you've got red hair and someone sent a memo around saying that they'd heard that everyone with red hair was more of a fuzzy people person than a real coder. Would you agree that people with red hair may well feel targeted?

[Apparently he doesn't have a PhD at all and has been misrepresenting this. Tch.]
