I am a trans pragmatist and advocate for trans pragmatism.
I agree that sex is fixed and immutable
I have no experience of gender, except that I am a woman with a personality
However I also acknowledge that some people for whatever reason feel deeply uncomfortable in their birth sex and navigate life more easily if they attempt to change the outside - clothing, hairstyle - into those more commonly understood as of the opposite sex in mainstream European society.
I don't think it especially matters why a person might do this, and I don't think it's always fetishistic. All I know is that my adult child is immensely more functional in their chosen form. I think the very strong intersection with autism is not taken into account enough on some of FWR who talk about transpeople as a homogenous group of perverted ill intentioned men based on social media posts of bad apples. Most trans people are if anything rather gentle and vulnerable people in my experience.
I think children should not be facilitated to transition and I don't think it should be actively taught in school, except to say that a few people are transgender and in the community they should be treated kindly like everyone else.
Those who love that person who has decided to transition then often attempt to use chosen names and pronouns because they want that person to feel accepted and loved.
Where things gets muddy is when such a person wants to opt into the rights and privileges of their new gender, or get very angry and/or upset when others recognise their transness and may use a pronoun that the person considers incorrect.
I understand why a trans woman would not want to use the gents toilet when out and about. They have specifically rejected being male.
However, they also need to be realistic that they differ from born women and have no right to those spaces.
Privacy and dignity for ALL is needed and posts on FWR often does not perceive this or care about it.
I think a pragmatic transperson acknowledges their past life, acknowledges that they occupy a liminal position, avoids inserting themselves into spaces that are specifically of their acquired gender, and seeks out a way to live authentically as a TRANS woman or man, using gender mixed or dedicated spaces where it makes a difference (eg my daughter attends trans swimming for dignity reasons, but could happily attend mixed cycling sessions as gender is less of an issue). I think so much of the issue arises from this mistaken notion that the only successful transperson is one who can travel through life unrecognised as their original sex. So much harm arises from this thought - the desire to "trans" children, the desire to access "women only" spaces, the anger and distress at 'misgendering', the wish for falsified papers such as birth certificate. Just acknowledge being trans and that this is ok.
