assuming that's the reason someone would want to identify as transracial
transgender people from what I understand (admittedly very little) identify as such because of their inner feelings of masculinity/femininity/attractions so on
but i don't think people wake up and say they feel their race internally
what is that?
how does someone feel black without any societal context that identifies them as such?
if it's based on the things they identify with culturally (like music or clothes or taste in a partner), that doesn't require that a person's skin be a certain color to embrace it
so i don't think the comparison is an appropriate one.
or if it is, i can't wrap my head around it.
