I haven't watched the new revival of Big Brother, as I think it already started to go stale over 20 years ago; but they showed a clip on something or other where they were meeting the new housemates and one of them was trans.
One housemate virtue-signalled and suggested that they should all go around the table and state their pronouns - why this was remotely necessary for anybody except the trans person, I haven't the faintest clue.
I mean, it's not even like the words 'he' or 'she' are remotely offensive, so why you'd be upset at being referred to the 'wrong one' if your appearance 'strongly suggests' which one people would naturally use for you, I do not know. Many very much non-trans people have, on occasion, been mistaken - on the phone, by people not looking properly or just making assumptions - and they all seem to have managed to come out the other side unscathed.
