Relevant part of NotDrowing's original post:
A couple of weeks ago I was chatting with her girlfriend and she referred to my neighbour as he so I got what the pronoun was. Today I was talking and I inadvertently used she when talking about the conversation with the girlfriend and also about a niece and blah and ... Neighbour was "It really doesn't matter. It's just a thing. I get it, don't worry." I was worried that I'd upset him because whatever my views are in general when it comes to an individual who I actively like I never want to cause offence.
I did not respond to this, because even though I disagree that we shouldn't correctly sex people if they're nice, I don't really care what NotDrowning does about her neighbour and she put it as a personal post.
But then another poster said this:
I wish there was a like button on Mumsnet but as there isn't I'll just say how much your post resonates with me. I would never, ever dream of misgendering the transwoman I know and that's partially because she doesn't give a shit about it, she just wants to live her life peacefully.
And I did respond then, saying:
But it's not misgendering.
If you want to collude in a friend's fantasy, that's absolutely your choice and I'm sure your friends appreciate it.
But please don't suggest that using the correct pronouns for someone's sex is rude. A man does not become 'she' if he's really really nice. My judgement of what pronouns to use is based on sex, not personality, depth of friendship or anything else.
NotDrowing then decided I was being very rude to her, personally, by using the phrase "colluding in a fantasy." She said that this was rude and that she felt that using someone's preferred pronouns was no one else's business because it didn't hurt anyone. Lots of rhetorical questions about does it hurt you, does it hurt other people, etc etc.
I responded that it wasn't rude to speak the truth, and:
Does it hurt other people? YES. It does, actually. Read "Pronouns are Rohypnol." Your lies only make it harder for women like me to speak the truth without censure.
NotDrowing then asked me what she thought she should do then, what was my great advice etc, and I said, do whatever you like, just don't tell other women they are being rude and misgendering for not doing the same. Then other people started scolding me for saying that to NotDrowning.
I stand by every word I've said here. I don't care if NotDrowning wants to join in the pretence with her friend/niece/whoever, but I don't want to be told it's rude or misgendering for me not to join in the pretence with her. That's all.
I hope this is clear now because what a fucking waste of everyone's time this is.
