If you erase sex as something recognisable, how do you know someone is trans?
Serious question. They become 'just another person' without any protected characteristics that can be identified.
If you cant see sex, you can't see sexism. You cant see homophobia. And you can't see transphobia.
These become meaningless concepts because you have removed the ability in law to identify them.
Otherwise if it's just about feelings anyone can claim they are trans, homosexual etc etc.
Imagine I woke up tomorrow and said I feel like a transwomen. Without sex as a definition point you HAVE to recognise me as a transwoman and my claim to represent transwomen. So anyone could claim anything and it all be utterly meaningless!
Without sex to define trans people you can't actually protect them.
The law has to be definable. You cant have a woolly meaningless concept that changes depending on whether observing sex is convenient to you at particular times. Sex has to be observable in ALL situations at all times.
Otherwise trans as a concept, manages to effectively do a Back To The Future on itself and creates a paradox where 'Martina' ceases to have ever existed.
The fact that those screeching about 'transphobia' haven't worked this out yet, amuses me no end tbh.
