hey i don't know anything about the person Kitchener that the stitch was named for (and i honestly wouldn't have guessed "dude" based on my experience of fiber crafting spaces so I clearly know even less than I assumed I did)
may I know what he did to earn your ire?
You're right about the typical gender breakdown of fiber arts spaces. There's no evidence that Horatio Herbert Kitchener even knew how to knit. He was a British colonial army officer who supported an initiative during World War I encouraging women at home to make socks and other knitted items for soldiers. The Red Cross distributed a booklet with a pattern including a grafted toe, and his name got attached to the technique. (source)
But more importantly, in his role in the British colonial army he was notably responsible for atrocities in South Africa during the Boer war. This included concentration camps in which tens of thousands of people, mostly children, died. The website I linked above says they were a direct model for the Nazi concentration camps, although I haven't checked out that claim myself.
Not really a person I'm interested in honoring, or who deserves to have an important knitting technique named after him.
