Wherein I dare to hope…
In which the author and a third grade teacher share mutual incomprehension.
The moment you know you have reached middle age, and are happy to do so.
She was participating (whether or not you noticed) and she was making comments before then. I don't see the distinction between the two conversations.
And there are (an incredibly limited number of) women or woman-adjacent people on this site, who have every right to speak up when they have opinions in public discussions, without being dismissed, and I'm 100 percent sure Sam wasn't trying to keep us out of the conversation and would welcome our comments. So you're on real thin ground complaining about them / us.
The only reason I went with feminist "not-men" is because I'm genderfluid. V is nonbinary but I believe prefers "woman" to the alternatives, however it's hard to lump the two of us together with one word because gender is not something people are used to talking about beyond a bindary. If you have a civil and more efficient way to name us as a group than I used, I'd actually welcome that, it's awkward as heck.
But if you care about this site and you don't actively want to keep the comments as 90+ percent male as they have traditionally been, what you're doing, joking or not, is counter-productive.
I'm asking you to stop.
