I'm a little cagey about these fundraisers- but FairPlay for women and the ons are without doubt a worthy recipient.
Sex is probably the most essential piece of information that attaches to us. When we announce a birth, it's 'a little girl (or boy) mum and baby doing well, 8lb'.
As a species we ask 'boy or girl?'.
As a woman when someone walks toward me I immediately check out- male or female?
On the pathology slab, they won't care our name or job, just our sex.
Sex matters and the ONS had better damn well realise that!
