I think you left out some context there.

Grace Hopper, one of the most accomplished computer scientists not just of her day but ever. Rose to dizzying heights in the US military because they needed her so much. A towering giant of the field. So when the picture of her comes up on screen, does the speaker say any of this? Does he acknowledge her greatness? No. He says she's wearing a cute hat. All her accomplishments and ability reduced to how she looks in a hat.

The problem here has absolutely nothing to do with the hat.

This debate is entirely moot without context. I imagined/read it as something like: >"...Ah, and this absolutely brilliant woman started that trend. Just look at her, a beacon blahblahblah wrapped in that cute hat."

If neither of us have been there, its pointless arguing the statement. My point is simply that when I do such talks I frequently inject humor into it, just the way he had. Reading it as a completely isolated comment seems highly unrealistic to me.

When you give your talks with humour injected, do people in the audience come to you afterwards and suggest that your remarks were unhelpful to some people in the audience, as someone did in this case? In essence, do people politely complain to you about what you said?

If they did, would you ignore them and carry on injecting your humour?
