And bad things in history won't be prevented from happening again just by censoring the words that describe them. It's probably the other way round!
And applying one of these words to elements of software or hardware is just a convenient way to describe the relationship between said elements. You can't offend an effing hard disk drive!
Politically correct language has morphed into a tool for some fuckwits to gain an illusion of popularity or power, at the cost of breaking language, one of the most important tools we humans have.
This is criminally stupid.
