The whole kerfluffle around pronouns centers around a singular premise. This premise was first asserted in the "Stack Overflow is Not Very Welcoming, it's Time for That to Change" blog post:
Too many people experience Stack Overflow as a hostile or elitist place, especially newer coders, women, people of color, and others in marginalized groups.
The only evidence that has been given that this is true is that (paraphrasing):
Some people have told us this is how they feel, and because everyone's feelings are valid, then it must be true.
I'm not going to re-litigate that here. And honestly, I think there's very little chance that anything I say here will effect any meaningful change at SE corporate, but I must try anyway, because I love this platform and its communities, and I see them being destroyed from the inside out over policies that I believe will not actually help the groups they are supposedly meant to help, and might actually hurt them.
I'm going to quote a passage from an interview with Bill Maher about political correctness, because he says it better than I ever could:
I grew up in a household with two liberal parents who were ahead of their time. My father and mother told me about civil rights. I knew what the right thing was. The difference is that liberals protect people, and P.C. people protect feelings. They don’t do anything. They’re pointing at other people who are somehow falling short of their standards, which could have changed three weeks ago. They’re constantly moving the goalposts so they can go, “Gotcha!”
When I was growing up, the most liberal thing you could do is not see color. Well, that’s wrong now. You see color, always, so you can register your white privilege. But I grew up in the Martin Luther King era: Judge by the content of their character, not the color of their skin. I still think that’s the best way to do it. Not see it.
If someone walks in the room, after a minute, I should not be thinking about color. And I am not. That’s how I have always been. I have actual black friends. I don’t think they want me to be always thinking: Black person. Black person. I’m talking to a black person.
The Stack Exchange platform works so well precisely because it has a philosophy of staying on topic. The way I used to moderate worked so well because I don't take sides. This is an international platform; you're never going to satisfy everyone's sensibilities.
But everyone can agree to form a community of professionals around a single area of subject matter, and the backgrounds of its participants should not matter at all. That's different than taking the position that we need to protect everyone's personal feelings, or that we must change the demographics of our sites because we don't like the numbers we get from our surveys.
Stack Exchange works so well precisely because, unlike forums and chat rooms, it focuses on that singular purpose. Dragging advocacy of political causes into the platform is fundamentally opposed to that purpose.
