Thank for your reply, Terence. Just to clarify, my issue with your "chromosomes" comment is not about Dr, Professor etc. It's actually about the fact that, for example, a trans man could have xx chromosomes and yet have the title Mr, meaning a title (any title) has absolutely nothing to do with chromosomes. Apart from this, as you have so many non binary friends, I'm surprised you are not up to date with current thinking around bringing "chromosomes" into conversations around gender. It's generally done when attempting to remind trans and nb people of the "immutability" of their "biological sex". Unfortunately, you seem to be stating a similar thing here by implying that "Mr" is an indicator of chromosomes, when it is very much not, and absolutely should not be. In other words, nobody sending you a parcel has any idea about your chromosomes unless they demand to test your DNA before they send you anything. Thank you for amending your form. At the moment, it looks like comments appear then instantly disappear, as if they have been moderated immediately.
