And if someone asked you to refer to them as PinkChestnut because they just feel so gosh-darn PinkChestnutty, because they just know when they look at you that you and them are really really the same inside, that's ok by you, yes? Even if their idea of what it's like to be PinkChestnut is pretty superficial, kind of offensive even?
And when a few weeks later they come round to use your car because it's PinkChestnut's car and they are PinkChestnut, everyone knows that, the proof is clear because everyone calls them PinkChestnut, you will be fine with that because that's just good manners?
Manners are an interesting thing. When they are reciprocal they make the world a little nicer. But some people take advantage of manners, especially the manners of women who have been told from birth to put others' needs first. Some people rudely grasp and take, taking advantage of the manners of others being too polite, too well mannered to challenge them.
So the point is not, has never been, that people want to be referred to a certain way.
The point is that they want to be referred to as something they are not, and if society accepts that it has consequences for the people who actually are that thing.
