black girl is definitely a stable part of the family. she's not from another crashed space ship or anything. the first trailer shows her getting on the ship in dry dock with the rest of the family. the second trailer has her spouting the line about it being an unwritten rule that robinson's stick together.
honestly, i'm fine with that. i couldn't care less what race the family is made up of, as long as it's not a talking point of the show. like, just don't even mention if she's adopted or anything. my favorite quote from gene roddenberry... he was doing a press tour for star trek next generation before it aired. he was sitting with patrick stewart and some douche reporter was trying to be all edgelord and was like, mr stewart, don't you find it odd that in the 24th century, the universe still hasn't found a cure for male pattern baldness? patrick stewart just sat there dumbfounded. he said he was angry, embarrassed, didn't know what to say. before he really even had time to formulate a response, gene buts in and says "i think that in the 24th century, people will have stopped caring about male pattern baldness."
THAT is how you address this. it's not about being color blind, it's about not forcing a race issue where one doesn't belong. can we just assume that in the future the world is a better place? HUMANITY actually means something? i mean i know that's asking a lot but can we just try it out?
