I have a real issue with this phrase. It seems to have crept into common parlance. I've just read it in a news report on SKY. I've seen it in a questionnaire I had to fill in for my local authority. It was in the charity commission doc about LGBA.
It's blatantly not true. Sex is observed, not assigned. I get that some people will 'identify' as different to their sex as observed at birth. I feel the need to 1. collect instances of use of the phrase 2. challenge use of the phrase. Anyone with me?
