As an IT guy I was always happy to use terms like Blacklist and Whitelist and my hard drives run in a Master / Slave configuration. What a straightforward and clear way of describing things. A few years ago my desk neighbour was a mixed-race lady who used to visibly wince every time I used the term 'blacklist' within range of her hearing. That puzzled me for a while because I was describing bad things as being black and good things as being white but not in terms of people, that would be wrong and illogical. I live in a world of logic where words do not have connotations beyond unfeeling bits and bytes and hardware configuration. Sadly my wildly emotionally colleague (technical authors live out loud) used to be visibly upset by my language, reading things into words that I never intended. I never got up the courage to actually talk to her about it. What I did do though was to stop using those terms and instead said stupid things like "blocklist" and "allowlist", much to the amusement of the head of operations who used to repeat back to me "awowist, what's an awowist? Is that a buddhist that is very happy?" But Stuart is an idiot (all Stuarts are idiots, sue me). I don't have a desk next to that lady any more but I'm happy to report that I didn't make her wince for a little over 18 months, if we ignore fast-food-Friday, which is a weekly moratorium on food smells and highly recommended for the morale of any office. I know I am on thin ice here and 'blacklist' is not in any way a reference to black people but if there are people who's lives make them sensitive to such a use of the word 'black', then surely 'blocklist' or something better is not that much effort. Although, some of my favourite people are 'block'ed from facebook, so I'd suggest "Stuartlist".
