A friend of mine got a warning for referring to a trans colleague by the wrong pronoun.
You see, I have no problem with addressing anyone by their preferred name and pronoun at all. I respect everyone's right to live in peace as the gender they desire to be. What I'm not willing to do, for many valid and complex reasons, is continually draw attention to my own gender, as is increasingly requested/required in many working contexts.
Where problems arise here is that the response is immediately aggressive and subjects the person using the undesirable pronoun to employers'/legal sanctions when a simple correction would suffice. Problems also arise from an equally aggressive TRA lobby who would like to re-categorize women out of existence and to tell us how we should view ourselves. Women are rightly bridling against this interference; it puts our backs up and we are likely to respond with a firmly-stated 'piss off'.
I don't have any particular objection to referring to myself as cisgender in the context of that discussion. But to become a ciswoman as a default category - particularly in order to accommodate people who are hellbent on stampeding over my own hard-win rights - no. Just no. The idea that 'woman' is a dirty or taboo word should have all women worried, whether they happen to 'identify' as feminists or not.
Like hell will I specify my female pronouns in the context of every interaction I'm required to have in the workplace. Want the statistics as to why: check out instances of male-on-female sexual harrassment at work, the gender pay gap, and myriad other categories showing why women have traditionally been disadvantaged in the workplace.
And suggesting that people who reason this way are 'cunts' says everything about the people doing the suggesting.
