gender and sex have historically been used interchangeably but the current conflation is not helping create clarity
That is a reason to stop using gender to mean sex. It isn't a reason to enshrinenit in law as meaning anything else.
A concession to get sex clarified as recorded at birth, biological or natal sex etc.
Why is a concesion needed? Sex means sex. It is a biological reality.
(people cleverer than me can define the definition)
Not in a way any 2 genderists will agree with.
gender identity should be a belief under Religion or Belief pc but in the current climate I think we need a clear definition and that it is acceptable to not have a gender identity.
Why? Do we need a law saying its acceptable not to believe the earth is flat, or to define and say you don't have to have a soul? It's not for the law to define every belief individually and specify that you aren't compelled to hold it.
It would also allow other elements to be set out such as a definition of non-binary, pronouns being limited to she/her, he/him, they/them and not the squillion variations, what transphobia is and is not etc.
Again, why?
It would help employers, service providers, schools etc. by providing clarity on when sex matters and the boundaries they can put in place to respect people who do (and don’t) have a gender identity e.g. third spaces, how to navigate sex based rights vs gender identity based rights, data collection etc.
This can all be done under current regulations about sex (or if necessary, belief; or gender reassignment if you really must but theres virtually nothing not.covered by the forst 2). No additional protected characteristic of identity is needed.
