There is no evidence that males who identify as trans are at greater risk than females.
Their risk of being assaulted, raped or murdered here in the UK is lower than that of females. And more UK males who identify as trans have become murderers in the last ten years than been murdered. And the latter were murdered by other males.
The risk both groups face is male violence. That does not mean this risk can or should or must be mitigated against by including males who identify as trans in the group of females.
As there is ample evidence of crimes committed by males who identify as trans against females (unsurprising, posing the same risk as all other males after all), such a move would increase the risk to females.
I happen to believe that increasing a very real risk to one vulnerable group to decrease a very real risk to another vulnerable group is neither acceptable nor necessary.
As for your career. I was also denied a career, at the same time as you, because I am female. Again, addressing the unacceptable discrimination you experienced for being trans does not necessitate dismantling the legal tools available to females to address the unacceptable discrimination I faced for being female.
Even if percentage wise the issue was more frequently experienced by males who identify as trans than females, a just society does not abandon attempts to address discrimination experienced by millions of females in order to help a few thousand males.
The fact that we live in a patriarchy goes a long way towards explaining why we have made far greater stridessince then in addressing discrimination faced by males who identify as trans than the oppression faced by females.
Can we do better and protect more people who identify as trans? Yes, we most certainly can. Do we need to undermine or dismantle the rights of females to do so? No.
And don't call me cis. I don't identify with my oppression.
