This article by the well known author Brynn Tannehill should finalize the debate on the use of "cisgender":
"The use of "cis" and "cisgender" should be carefully examined. There are people who strenuously object to these words being applied to them, even if the words come from an academic background. Just as my feelings on certain subjects should be respected, so should the feelings of people who dislike these labels.
It also needs to be asked what using the words gains us....The conclusion of many organizations is that you should not use either "cisgender" or "cis" in any sort of public narrative. ...Even inside the LGBT community the words have a very negative connotation. When someone is referred to as a "cisgender lesbian" or "cis gay man" by a transgender person, it is often in a negative way. The addition of "cis" or "cisgender" is used to imply a certain level of contempt and a desire that they leave discussions on transgender issues. It also implies that they don't, can't, or won't ever understand transgender issues.
...However, using the word "cis" or "cisgender" is not necessary to do so. Just as no one ever called me "tranny" and meant it in a nice or affectionate way, many LGB people have never been called "cis" or "cisgender" in a way that wasn't accusatory. Therefore we find common ground in disliking a word because its context has always been nasty and demeaning when applied to us personally.....As a result, "cis" and "cisgender" should be used sparingly in public discourse."
I agree with the author "The conclusion of many organizations is that you should not use either "cisgender" or "cis" in any sort of public narrative." and I think it's time the Paizo boards joined this movement.
