Sure. And as with a lot of English, it isn’t totally clear has ‘xe’ is even meant to be pronounced. (I assume like ‘ze’).
Perhaps a nicer sounding version would be ‘ce’. Or whatever. To be honest, it really doesn’t matter to me. I’d be happy to just call literally everyone “she” or “he” or whatever. I’d suggest that we just use “he” for all genders, because many people on the internet seem to be doing that anyway; but obviously that would be upsetting to people who have been fighting for gender recognition. Pushing for “she” might be a bit better, but not by a lot. … So we’re probably in this mess for a long time. But I reckon if we just shake it up just a little bit as individuals, using different words and such, we’ll eventually start to see something change more widely.
