I used the words that seemed the most obvious way to express myself. I would have had to look up the term cis to make sure I was using it the right way, and there wasn't a good reason to. The fact that someone could possibly be offended by the use of the words I chose shows part of the problem. That's like saying you think "Italian-American" is ok, but "An American citizen with Italian ancestors" is offensive. It's a clear, well understood description of the trait being discussed that expresses no judgement. It _cannot_ be offensive under any normal circumstances.
