Maeve at L'Esprit D'Escalier has the succinct critique of common objections to the word “cis” that I've been looking for, Intro to cis and why having to write this annoys me.
Louise Mensch said yesterday on twitter that ‘cis’ is “an offensive term that I don’t recognise”. This inspired the tag #ThingsMoreOffensiveThanCis which is about equal parts hilarious-things-that-aren’t-offensive and really poignant transphobia.
But, I accept that there are people who may not yet have heard the term ‘cis’ and may want an intro. The briefest definition I can give is: Do you know what ‘trans’ means? It’s the opposite of that.
