But they kinda do make such jokes. They don't do it when you're around. If you managed to overhear it, you'd be amused and shocked, "uncomfortable", I guess.
I think, extrapolating from Richards' definition of racism, which is that only the historically powerful can be racist (white can be, black cannot be), then she doesn't believe, generally, that women can be sexist. So she can make socks-down-the-pants jokes, and have no moral qualms about making you uncomfortable. By definition, she can pretty much say what she likes; you, as a man, cannot.
I think that we've come a LONG way from, say, the atmosphere of the fifties, when men were pigs and proud of it. Consideration is now part of our modern complete breakfast.
But. At some point, being "uncomfortable" become a passive-aggressive way of acquiring iron-fisted power over others. In this case, she misheard and over-reacted to others making much the same kind of joke she herself has tweeted. If she has tweeted such, she has spoken such, so she is no stranger to silly off-color humor. So the issue, again, is who has the power here - she does.
Another issue is the atmosphere of watch what you say, watch what you do which is, frankly, VERY uncomfortable to live with. It casts a pall, not because you can't make dongle jokes, but because, today the dongle joke, tomorrow the fill-in-whatever-someone-wants-censored. The function, once written, can be supplied any argument. Power over speech, over action, should be limited, not open-ended. She ended, or tried to end, the jobs, perhaps the careers, of two men. And she managed one. And unintentionally ended her own job. Why - perhaps because she misapplied her power in the workplace.
One might wonder why I go on about surveillance in other posts, and this is one illustration why - in a world where a camera and mic can be anywhere, you are in a prison, no matter what comfy chairs there might be there. Privacy of some sort, even if it is just for talking with someone sitting next to you, is essential for a civil society - living in fear of sudden discovery and loss of career is no way for a human to live. Humans who must live like that are pretty much prisoners.
Eh, 'nuff.
