Thank you for sharing the definition and usage of "cis."
I had never heard of that. It is, of course, complete nonsense.
How extraordinary that we must now have a PC prefix, meaning "normal, non-freakish."
I had never heard of the term either. I had to look it up. I don't run around in such “educated” circles these day to have been familiar with the term. But I expect that the multicultural classes these days that college kids are forced to attend to graduate include such terminology indoctrination.
