If this is true, the person who made the decision to suspend the Labour member should themself be suspended for transphobia.
Every trans person knows that transition does not mean actually changing sex. Every decent, honest transwoman knows that it's not possible for a male-bodied person to experience or to speak from experience about menopause.
People who insist that men and AMAB trans or nonbinary people should be allowed to speak about their personal experience of menopause are blatant (and for the most part hateful) AWAs, not TRAs. And they are transphobes, setting trans people up to look like they are categorically delusional and anti-woman/misogynist. These people do not have the firsthand experience, and every single one (minus perhaps small children) knows it.
If UK Labour have (had) any connexion to its history of defending marginalised and expolited groups, it will (would) speak up for women now.
