I haven't lost any friends over my feminist GC position, probably because many of them are middle aged and tend to be no nonsense types. As for family, all but one are strongly in support of my views. My DSD is keeping her eyes open for any Stonewall/Mermaids propaganda in her DC's schools. Her DD is at a Catholic secondary school, which my DSD hopes will act as a protective factor. Her DS joins his sister next term.
My sons, who are in their twenties, tell me their friends not only don't believe in gender ideology, they simply can't take it seriously. They'll say "How dare you assume my gendah?" in tones of mock outrage and fall about laughing.
The only person in my extended family who supports gender ideology is one niece, privately educated and very sheltered, who is at an extremely woke university. She plays university rugby and other sports in which strength is key. Her dad is both baffled and appalled to find her so totally unrealistic about the dangers of playing against a mixed sex side. He was a serious athlete as a young man and, though one of the least political of men, is both knowledgeable and angry at the harm being done to women's sports by transactivism.
The main reaction I have encountered among friends and family is disbelief. Most people haven't the faintest idea what's going on or any of the arguments being put forward. Back in 2018 when I talked to all my friends on different occasions about the campaign for Self ID most of them were quite sure I must have got the wrong end of the stick. I had to show them evidence on my phone before they believed me.
Once I'd convinced them it was really happening they were horrified that something as momentous as Self ID was being considered without a widely publicised national debate. None were in favour of the idea.
My friends are far from unusual in their reaction to gender politics. When I leafleted with other women about the Self ID consultation over several weekends in autumn 2018 I only came across two out of dozens of people we spoke to who supported the idea. Interestingly, men cottoned on to the risk such a policy posed to women instantly. It took the women a few seconds longer.
