So just for interest, I sent this link to my Labour MP. This was his reply:
"Thanks for the email. I have had a look at the thread and the theme seems to be that the contributors are largely unhappy that the Labour party view trans women as women.
I think you know my position on this: trans men are men, trans women are women and being non-binary is valid. As an ardent equality campaigner I have never believed we advance the interests of one group with a protected characteristic by removing or limiting the interests of another group.
As Plymouth's first ever out MP, I know the fight for equality is a long one, and that the rights I enjoy as an openly gay man now were similarly attacked in the past.
Labour has strong policies in support of women and strong policies in support of trans people. I believe you can have strong policies to promote the best interests of both groups, acknowledging the obvious cross-over. I will continue to make the case for equality and do so respecting those who may currently disagree with me.
This may not win your vote if your view is in line with those expressed on the thread, but I would prefer to do the right thing and put forward a position I truly believe in because it respects my values than compromise that fundamental belief I have in equality to chase votes. Others may feel comfortable doing this, but I do not."
He deserves on many levels to lose his seat next time round.
