Of course anyone can "present" in in any way they like. There are no laws about what men and women must wear or the names they can use! Show me where the Equality Act says that the terms man and woman are about presentation not sex (clue: it doesn't)

EA2010 states a person is protected by law even if they are "proposing" to undergo the process of "gender reassignment" by changing "other attributes of sex". These "other attributes" can be purely presentational. EHRC Statutory Code of Practice page 34 gives practical examples

Yes they are protected by law against discrimination because of the protected characteristic 'gender reassignment'. They shouldn't lose their job, be harassed, be refused service in a restaurant etc... This does not mean that the protected characteristic of sex has changed.

Agreed, the protected characteristic of "sex" has not changed, but it means a transwoman (which includes a male who has had no medical changes) is regarded as the female sex in law. Fundamentally it is about the mental-health based rights of males to express their femininity

No it doesn't. If the protected characteristic of sex has not changed, then the protected characteristic of sex has not changed. The protected characteristic of sex says nothing about men not being allowed to 'express femininity' (because that would be sexist twaddle)
