Strategically, knowing what a woman is is only an advantage if you're needing to gain points against Labour (or, theoretically, another TWAW party).
In the leadership election it's not going to be that much of an issue, because the party aren't that bothered by it.
It may be useful, if not joining the party to vote, to write to Tory MPs making sure they know it IS an issue and a reason for voting Tory.
