I don't see how it can be done either. I can see the appeal of choice and choosing one's identity, but in patriarchy, which is the current global regime that we all live under, I think it is a pipe dream for most people, especially women/the poor/people of colour/etc.
I think we need the revolution first and we need it to happen everywhere, for everyone, globally. I don't think self-identity will bring about the revolution.
And yes, we should interrogate what truth is and challenge monolithic society (which is what feminism does), but surely the very meaning of monolithic is that these things are massive and very slow, and resistant, to change.
I can see that maybe a few privileged people can change things for themselves as individuals using this method, but that doesn't mean a global and historic system has changed. And if these few privileged people claim that their exceptional situation is some kind of truth for everyone else (if they would just get with the programme already) they aren't helping the bigger picture and they are potentially damaging things for those less privileged than themselves because that truth is individualistic and kind of suggests that others who do not achieve it, have only have themselves to blame. And that disappears the truth of others which is that choice is currently an illusion for the vast majority of us and that global systems of oppression are structural and need to be fought on class levels.
(I am not saying that you personally do any of these things Corey.)
It reminds me of myself when I was a young feminist and I thought that being a feminist was quite easy. I thought it was easy because I was young, healthy, educated, white, childless, inexperienced and had the combined blinkers of inexperience and youthful optimism that allowed me to be pretty selfish and relatively free.
Radical feminists have an expression that you may be familiar with which is "radicalized by motherhood" . What this means is that becoming a parent (mother as a woman) is a like a wake up call to the realities of female existence in male dominated society. And it is something that is entirely rooted in biology. You can self identity all you like but you are the one who is going to be carrying and birthing a baby and that will change your life in ways it will not change a biological male's life. Indeed it changes the lives of childless girls and women too the world over. And it had already affected your life from the very day that your (biologically female) mother gave birth to you, you just weren't analyzing it because it was presented to you as the natural order and you were socialized within that.
Self-identity and its cousin 'agency' strike me as very male centric concepts.
