@croc : Fair enough. However, "cis" is a term used almost exclusively by one group to label people in another group. It is virtually never used by the people labeled with the term as a self-description- i've never encountered this at least.
I have
never seen it used in a positive way (eg "cis people are so cool!"), and often in the disparaging way it has been used here.
Labels like that, that are used for "othering", are sometimes seen by some as problematic. Like in this thread, with "tranny".
Since cis-gender applies to at least 95+% of all people, perhaps a marker is not needed very often? And in the rare case where it is, maybe "non-trans" would do?
As to the claim that "cis" is a just plain old non-offensive neutral term like "straight"- I'm a heterosexual biological male in a monogamous marriage with the woman who bore our son. I assume the mustache in my picture is kind of a clue that i am "male-presenting".
But i don't like being labeled as "straight". Not one bit.
First of all, i'm old enough that the opposite of "straight" was not "gay", but rather "freek" (kind of like a hippie except younger and into like Alice Cooper and Bowie not the Dead- young and countercultural). In 9th grade english class (1972), we had to write an essay about "Two kinds of people". Mine was about "freeks" and "straights"; my gay best friend's was about "fags" and "hardhats" (meaning construction workers; look up the "Hardhat Riots" that had just taken place in NYC between anti-Viet Nam War protestors and construction workers). Neither of us would have understood you if you had said "straight" and "gay" are opposites. When i use the word "straight", which i do fairly often, i usually mean "doesn't smoke reefer", or maybe "non-countercultural and uptight".
Second, it makes my sexuality sound constricted and boring. It isn't a term of praise, but rather a negative value judgement that what makes your dick hard/your pussy wet is somehow better than what makes someone else respond that way. We none of us are responsible for what makes us horny. Judging others for what gets them horny is lame, whoever is doing it.
If you call me "cis" or "straight", am i going to fly off the handle and say you are erasing my identity and making me unsafe? No, because that would be really silly. But it doesn't mean that those terms don't annoy me when applied to me.
