I'm sure that's very close to what actually happened, and that this phrase is not hyperbolic or trying to portray "maybe we should treat people equally and not pre-assume things about what roles they should have based on their race/gender" as an extreme radical idea when it should be the default stance.
Viewed charitably "[it is off-topic to be] doubting the validity of scenarios" is fine (so long as it goes either way), but the question I'd ask is:
Is "debating whether bias exists at your organisation" on-topic for a future session, or does that conversation just never happen?
I'd also like to know if "Unconscious Bias training" ever references the "Implicit association test".
Please don't criticize my portrayal of someone else's impressions of those programs as if that was my own opinion. You are free to watch Damore himself speak about that in the several taped interviews he has given since being fired.
