We do need to talk about Labour.
So I see Baroness Chakrabarti, the shadow attorney general no less, is using the power of the word ‘self ID’ in an interesting way in the media today.

’Labour has challenged Theresa May to show she really is a feminist by backing reform of Northern Ireland's strict abortion law.
Shadow Attorney General Shami Chakrabarti said women in Northern Ireland "have been let down by privileged women and men for too long".
^She said the PM was a "self-identifying feminist" and "the test of feminists is whether they stick up for all women".
Following Ireland's historic vote, the PM has been urged to liberalise NI law.’^
It’s interesting to read this quote if you replace the word ‘feminist’ with ‘woman’ and then compare that to labour’s policy on legal gender self ID which takes self-identification extremely seriously 
I mean, it’s almost as if people in Labour do actually know that self-identification, is not a trustworthy indicator, of being that thing (Nor of supporting the others within that category that you have just nominated yourself to...?)
