this person is referring to a dichotomy in the black American slave caste, where people that worked in the fields were considered different than people that worked inside the house. the adjectives being "house negro/n**r".
It is used to invalidate the opinions of someone proclaimed as "black" that doesn't have consensus with a community that is pretending to be amorphous.
There have always been black Americans privileged enough to choose causes like any other American, while being lumped into the identity politics from all factions of the country. Even Martin Luther King's letter from Birmingham Jail (1953) references this.
I don't speak for anyone, and I am aware of black American people in my life that did bring up the "master/slave" terminology in computing as problematic and offputting and insensitive. The people in my life are of an older generation than me. The github issue, as this article points out, does not have a "slave" context only a master. To some that doesn't make a difference.
I am speaking for myself and like I said I agree with what the person in London wrote.
"Microsoft stops selling software to American police departments" is a good response to BLM. "Microsoft changes 'master branch' to 'main branch'" is pointless deckchair-reshuffling that signifies nothing.
By applauding the change of a noun that has the most tangential possible relationship with slavery, aren't you letting them off the hook of doing anything substantive?
?!?
It basically means a "house slave" that was well-treated and is therefore sympathetic to or on the side of the white man. The anytonym is "field n-word", a slave that worked in the fields, which I probably heard more often as people sometimes identify as that term. E.g., if a guy is talking to his buddy who has a nice ("cadillac") job situation, he might say "I'm just a field n-word."
What do you mean? It looks like Trump got a higher percentage of black votes in 2020 than 2016. The change is larger than Hispanic votes even:
