The thing is, male people are not having ‘vaginoplasty’ and no medical professional should be calling any male extreme body modification procedure by that term.
There really is no comparison between a female vagina reconstruction and a male having an artificial cavity inserted into his groin. It is not ‘valid’ to describe the procedure using the same term.
it is also not transphobic to point this out.
This is where you are demanding that your subjective belief about yourself that isn’t reflected in material reality is treated as if it is materially real. A male person having an extreme body modification where a cavity is sewn into his groin does not have a vagina in any way. The language used has been misogynistically repurposed.
A male person demanding that their artificially created body part that is not a vagina is referenced in any way as a vagina is a male person demanding that other people act as if that male person’s subjective reality which has no basis in material reality is materially real.
The accurate discussion and description of that procedure and rejecting that false repurposing of language is not transphobic.
