Oh, I don’t know. It’s not my choice of how to explode pernicious ideas about gender/sex (and yes, I actually do mean both of those!), but I can sort of see it.
I don’t think it’s any more harmful to the individual child than imposing a more mainstream gender ideology on them (even just the gentle gentle very centrist stuff like girls’ less hard-wearing shoes or whatever). I have never been ambiguous with my children themselves about their sex and what it means, but I also recognise that the gender ambiguity with which they often present (long-haired sparkly DS, blue-clad rough&tumble scruffbag DD etc) helps them avoid being reductively pigeon-holed by randoms in the street and means they get a bit less drip-drip sexism. Particularly with DD, who is my second child, I have seen the suffocating ‘prettiness’ she can be tarred with if read as female. I can see the appeal of avoiding this experience for a child’s own benefit.
In terms of the wider impact - hmm. To an extent, I think we’re all partly using our children to push our own agendas, at least until they’re old enough to turn round and throw them back at us. Definitely when I tell my DC they can wear and play what they like (as long as it doesn’t hurt anyone), I know that for some regressive people that’s going to be provocative and I see that provocation as a definite bonus. Likewise tbh I think it’s ok if a non-binary child (and I do disagree with Kori here, I think they are raising their child as non-binary just as I am raising mine with the labels that correspond to their genitals) makes people think and wonder about their own gender ideas. I don’t think its desirable that we all become ‘they’, but I think it’s fine if some do.
I don’t think conforming to norms is apolitical.
I winced a little bit reading the article (because ‘ooh look at me!’ isn’t a look I’m comfortable with generally, and for me it sat strangely in a newspaper publication - different if it was Kori’s own insta or whatever), and like I say it’s definitely not for me, but I think it’s legitimate and compatible with other, feminist, readings of gender, such as my own.
(I don’t think I’m full on GC or pro trans, though; I think mostly these are issues to consider on a case by case basis rather than a whole systems view. I realise that’s not the dominant take on MN.)
