There has been, over at Pam's House Blend, a row about whether the term cis-, used by many trans people as a way of describing non-trans people, is offensive; it is a row out of which I have stayed because I have been busy with other things. From voz_latina this link to an excellent post about the whole controversy.
As Voz says, pass it on.
Later It appears that, for whatever reason the blog containing this post has been deleted. Given this, I shall probably delete this post in a day or so.
