This was supposed to be a safe space for black mumsnetters to explore their experience (and discomfort) with the GC appropriation of a specifically raced experience of passing/stolen identity as isomorphic with trans requests to be treated with respect for their chosen gender.
At the best of times this is an interesting conversation to have—I mean I would be interested in it as an anthropologist because of the complicated history of alliance, passing, and demotion/outcasting which underlies movement between castes, races, or religious groups. Historically women, especially, have often chosen or been forced to move identities when they marry into another group: upper castes become lower castes, jews become christians, black people live as white, white people choose to become black—in the 17th snd 18th century, famously, white captives became Indian through adoption and choice, refusing to return and resume life as white even if offered the chance. Movement between groups, adopted identities, the fight for social recognition, is nothing new. Sometimes those people were choosing to “pass” from a disfavored social status to a more favored one—jews into Christians in spain, blacks into whites in the US. Sometimes individuals pass from more favored to less favored by choice and self adoption—read The Sea Captain’s Wife, The Sweeter The Juice, (black into white) and The Color of Water for three different historical/biographical accounts of this process. All instances of a nominally white person living as a person of color or in the community can’t be collapsed into Rachel Dolezal.
The problem, as I see it, with the GC appropriation is that it is just a trite appropriation of a complex issue. Its just used as a kind of forced teaming, a gotcha. Why do black people get to reject Racel Dolezal while women don’t get to reject trans person X? We get versions of this wail all the time from white people who resent any privilege they don’t have access to. If black people can complain about slavery and get social approval why can’t I call paying taxes slavery and get social approval? What the GC argument boils down to is not solidarity (I support your struggle) but simply envy (you seem to have the ability to police the boundaries of your group and I want the same right).
