The character is transgendered and says they are including their previous name in a throwaway line.
As usual with the transgendered community they can't decide what they are angry about but they are angry.
1) The tokenism, why is it just a throwaway line and why aren't there any transgendered characters in your multi-species, multi-gendered, multi-race, multi-faith, multi-sexuality and Scottish crew.
2) Transgenered people never refer to thier old name (my experience in this is true for those who are, however I've seen people I don't know personally that they do sometimes). Any arguement that they don't mention they are transgendered is untrue unless they are full transitions they are almost like Vegans.
3) Grrrrr outrage grrrrrrr
And then there are those shrugging their shoulders going why do we perpetually hurt ourselves and peoples observation of us.
