This is my 2 cents about this whole matter, I will not discuss politics ever again on this site. I hope you do the same..
Someone in this site mentioned that the word master offended her all these years because she is a "product of slavery".
The fact is, you don't have to have dark skin to be a product of slavery. Slavery existed in the world since the very beginning and sadly it still exists in the whole world today, not just in some parts of it.
I'm the product of genocide (Armenian) but I never find any word related to genocide offending, including the world genocide. I don't find the "kill process" logic offending in Unix or anywhere else. Because I realize that you are killing a process, not a human being.
I never thought of "master" as a slavery term until people started talking about it in that way. It seems Racism is in people, not in words. If you wanna see racism in a word, then you will. Master in git had absolutely nothing to do with slavery.
What about when people talk about "master classes"? Are those slavery related classes? "Master of her/his domains"? The word master has many meanings: https://www.merriam-webster.com/dictionary/master
People are resisting this change because they see awful politics hiding behind it that is invading the programming world. A real slavery is happening here, where some people that have nothing to do with DEV are FORCING (like a slave master would do) developers to make changes for no good reason whatsoever.
Next is blacklist and whitelist. These 2 terms have nothing to do with the races... It's the concept of light and dark, day and night, good and bad. Why white is good? Maybe our ancestors thought the day/light was good and the night/dark was bad for obvious reasons. As a child, I used to be afraid of the dark (kinda still am, who isn't?). There's some religious historical relations as well which came through our ancestors to us, the whole idea of light vs dark, good vs bad, somehow coined with white and black when put as colors.
White people are not really WHITE! They say our skin is pink, I'd say we are beige of different shades (a pale sandy fawn color). and Black people are NEVER BLACK. They are light brown of different shades. Stop calling people white and black. We are none. (https://en.wikipedia.org/wiki/Human_skin_color#/media/File:Felix_von_Luschan_Skin_Color_chart.svg)
Morgan Freeman, when asked about how to end racism, he said: "Stop talking about it!" (https://www.youtube.com/watch?v=WNM4txmV0Lc)
