What you are doing here is turning something that is quite likely completely unrelated to gender, into a gender issue.
This is not useful. It doesn't "fight sexism", it makes the battle harder to fight because you end up fighting an enemy that doesn't exist. You're moving the goal posts.
And I am 100% for fighting "unconscious biases", but my point is this isn't even necessarily that.
Please read some of the comments here. Please read Veronika Hubeny's reply. None of the people who were actually involved in this think it has to do with sexism/gender. Great, a woman stood up for another woman, an awkward moderator was humbled, and we all learned and felt a little better at the end of the day. Now, by turning this into a sexism issue, trying to claim that the moderator was "mansplaining" without even bothering to figure out whether it is conscious or not, not only are you drawing a new dragon to fight against, but you're subjecting a moderator to potential bullying and harassment.
None of this is motivating. It's pretty dreadful in fact, and the idea that you might be subjecting an innocent to this sort of treatment is turning people off the cause -- in fact, it's far likelier to make them even more cautious and tread even more carefully when talking about it (which through continued self-censorship ends up turning the entire community into an echo chamber).
Please focus on the real dragons. Changing people's views and behaviour takes focus and patience. Look at the environmentalism and lgbt movements: They're fighting for issues that the majority of people aren't (directly) affected by, but they're winning because, the majority of the time, they use other people's compassion to fight real issues.
Here instead, you're taking something we've all been guilty of in our life (talking too long and over someone else) and turning the person into an enemy because it might have had something to do with gender. Do you realize how horrifying that is?
