I will tell you honestly, that I believe you are the one letting your smugness cloud your view of reality, not the other commenter (indeed, I read their tone as matter of fact, not smug). No one is obligated to share their mother's personal information in order to prove a point to you. When you say you're presuming good faith and then include a string of insults in the same breathe, it's pretty unconvincing. Were you not entrenched in your position and holding other people's views in contempt, I think these observations would have been obvious to you before you hit "submit".
I hope you'll consider taking a step back and reflecting on whether this is how you want to interact with people and what it is that brought you here.
I'm not sure what troubles our flagged dead commenter more, that there are female math professors in the world, or that they have children that might comment on HN.
FWiW:
To the assertion that there exists at least one Emeritus Professor on mathstodon.xyz -

To the request that "that guy" provide social media accounts of his mother, her friends, their nom de guerres, discussions, etc .. I'm altogether unsure of whom "that guy" might be.
Cheers for your response, I'd have gotten back sooner but <shrug> Timezones :-)
