I had a little bet with myself that a lot of the responses on here would be along the lines of "politically correct claptrap" moan moan. And I was right. A lot of pearl clutching and fainting over what is a pretty harmless change to terminology. What's the harm in replacing whitelist and blacklist with allowlist and denylist? The new terms are just as concise, and far more descriptive of the actual intent.
I can't speak for BAME people any more than I can speak for all white people. But given the context of US history, why should anyone be surprised if at least some people find terminology like master/slave offensive, even if no offense is intended? Most of us are IT professionals, we work with computers every day, we know that it isn't really that hard to go through a codebase and remove terms that regarded by some as problematic. Why do so many professionals who claim to be calm, reasonable people arguing simply from a position of logic get so upset about this?
And as for some of the other arguments I've seen on threads below, they show a distinct lack of empathy, understanding, or attempt to put yourself in someone else's position. The claim that there is no racism unless it is intended is patently ridiculous. Who remembers Danny Baker tweeting the picture of posh people with a monkey in children's clothes after Meghan Markle gave birth? Danny Baker probably didn't meant that as a racist jibe, but it sure as hell looked like one to a lot of people. Because it so closely resembled many other provocations that *were* meant as racist. In the furore that followed that incident, and his sacking from the BBC, there were lots of (mostly) white folks explaining to (mostly) non-white folks how wrong they were to be offended, and missing out the fact that whether meant as racist or not, the tweet was genuinely offensive.
If you consider yourself as a well-meaning liberal who is "beyond race", then at least have the decency to stop telling other people when they should and shouldn't be offended. And if you are genuinely racist, then at least own it rather than gaslighting everyone with your insistence that you aren't.
