You don't magically stop being a woman if trans women are accepted, I find that an utterly bizarre thought process
You don't stop being of the female sex, no. But woman no longer has a tangible meaning if it includes men too.
People would need to clarify if you were a female woman or a male woman. It wouldn't mean anything in it's own right.
I find it disconcerting now when I read about something aimed at 'women' because I no longer know if it's referring solely to me (a female); is aimed at me and TW; or, in the cases when I've seen things open to 'self identified women', whether it even includes me at all - as I'm not a 'self identified woman', I'm a woman because I'm female. Not because I identify as one. I don't 'identify' as anything.
Already the reliability of the word is impacted.
My workplace has already implemented no gendered language. There are posters in the staff room at work instructing us not to refer to children as girls or boys just in case. Which is hard when you really just want to say, "good girl/boy" to a 5 year old as they quite like it!
I'm autistic. I'm one of the women who is impacted by this. I also find it mentally painful and physically distressing to be inaccurate or lie so i don't think i could ever refer to a TW using female pronouns. I would use their name or the neutral they/their (for all its grammatical inaccuracies!) But, for some, this still wouldn't be enough.
I dont know if my protection under the Disability/Autism Acts would extend to this.
I can't even use people's nicknames or abbreviated names once I have got to know them - I use the name they were introduced to me by forever. So it's nothing personal.
I'm most baffled on this thread by the patient, eloquent and well constructed arguments given by people on the GC side with so very little from those on the other. Just, "well I dont agree with you" with very little to no engagement with the points made.
