If you must know, the wife is being sued for malpractice and the job from hell? Yeah, not going to get my back pay and I won't get any hours from it, so I'm also going to lose my health insurance. Satisfied?
So. Words like "straight" imply that in some form or another we'll be talking about "straight" vs. "gay" or "queer" or "literally any sexual persuasion outside normative practices." I also had exactly two minutes to type out what I said, then spent the day battling the union, dealing with contractors and getting mired in a 4-hour lunch downtown, and spent the ten free minutes I had dashing out the two comments on this page. If I had it to do over again, I would have said "the way cisgender is used in this article demonstrates it wasn't written for me" instead of "in a sentence" but, you see, the phone rang to let me know that my career might be over so I hit "reply" and moved on with my day.
So yes. I could have been more nuanced in my speech and yes, it hasn't been the best of days. I sincerely appreciate you being condescending about it.
