I have a close friend who has 2 DD and I had always sort of assumed she would be gc.
Last time I mentioned the subject to her she was all 'but what about people who are born in the wrong body' so I let the subject drop.
When I saw her recently the subject came up again and she said she disagreed with me (fine) so I talked about my concerns in terms of boundaries - mine being if you have a penis I don't give a shit how you identify but please stay out of female toilets/changing rooms etc.
She then went quiet and the conversation changed. Something she said reminded me that she's a long time Guardian reader and it all made sense - all those years of reading it has really affected the views of someone who otherwise would be very gc - she's definitely a feminist and agrees that gender is a social construct - - bollocks--.
Don't have any conclusions but wondering if anyone else has had any similar experience?
I will keep dropping gc comments into our conversations though - and keep talking about boundaries.
