It would be clearer for them to just state that from the list of protected characteristics, it is not a hate crime to discriminate against someone because of their status vis a vis:
-Age,
-Marriage or civil partnership,
-Pregnancy and Maternity,
-Gender reassignment (not the same as a 'gender identity'), and
-Sex.
Only women will be screwed over on pregnancy and maternity, and the losers when sex discrimination rears it's head. The transgender identity also punches down on women disproportionately (some may argue the gender reassignment provision does that too).
Guess what sex is disproportionately affected by the characteristics omitted from the hate crime list? Also the sex where the dis-benefits fall on the hate crime list.
I'm sure it was a complete accident, and not by design, or illustrative of whose interests take priority.
