There is SO much information on this board. Even 6 years ago, I spent months just reading and rarely commenting. Because my own child had come home with a new group of friends and out of 7 of them, five over about a six to twelve month period declared they had transgender identities. I wanted to find out more about what was happening.
However, what I quickly came to realise is that this umbrella term 'transgender' really is very very broad. But I also feel that this broadness has been leveraged by extreme transgender activists (those who prioritise gender over sex even when sex matters) who, I gather, you have also identified. And that those activists make sure that no one discusses the groups separately.
They leverage it this way so that people like I assume, your daughter and Seethlaw, are grouped tightly with male people who very deliberately ignore female people's (and I mean all female people) boundaries. There unfortunately are no convenient terms to separate out the discussions.
From my experience on this board, people like your daughter are considered part of what feminists campaign for. That is, sex based rights for all female people, whether they want them or not. And generally, they are included when we discuss the needs of women and children. And the majority of the pushback is on the male people who have transgender identities and their demands.
Now, obviously, part of that discussion is about language which you have noticed. And you have also acknowledged that you have made your choice about language, but it is not based on your daughter's demands. I think people have attempted to point out that even though you do this, that even then there is potentially some harm in allowing those language changes at a collective level for women and children. It is not personal though. I understand that it may feel personal and that when you look at it from at the level of the individual it really may not feel harmful. Yet, when you start to see the effects collectively, you may or may not gain a different perspective.
I hope this is helpful and doesn't come over as condescending. That is not my intention at all.
