I think there’s a huge amount of peer indoctrination and peer pressure about gender when it comes to people working in the “birth world”.
Especially those of a crunchy disposition - midwives, doulas and mothers alike. Anyone who tends towards the alternative end of the mothering spectrum (the sling/cloth nappy women, who tend to also be huge advocates of extended breastfeeding, and other non-mainstream approaches) who also tend to be of the left politically, quite hippyish etc.
A friend of mine has a sling business and for a brief time was sharing a lot of gender-y stuff of social media. I was a bit crushed actually, because she’s lovely and I knew she was simply resharing content that her peers and colleagues were sharing. Because that’s what you did. I couldn’t believe that she believed it.
A year or two later and we spoke about gender ideology. She admittedly she’d kind of sleepwalked into wokeness purely because of the circles she moved in, and hadn’t thought about it deeply enough herself.
