What I love most about this thread is that I’m seeing usernames that I don’t instantly recognise, so either everyone’s name changing or the lurkers are delurking to say their piece. To all lurkers: bloody good on you. Welcome to the conversation 
Personally: no, I don’t feel on the wrong side of history. Leaving aside the polarities in all of this, the ones on the wrong side of history are never the peaceful ones, those who welcome debate, those who question doctrine and, well, women.
I’m sure there are lots of examples someone could grub up from yesteryear, but realistically how many women go out of their way to start wars? How many women, compared to men, commit violence? Commit sexual violence? Take specific careers and positions so they can access and groom potential victims? How many women give up years of their life training and volunteering and cultivating an upstanding member of the community reputation, so they can abuse with impunity?
So for me: I don’t think you can change sex. I was, and have always been, and still am, happy to be kind to those few people who have genuine dysphoria and cannot live with themselves in the body they were born with. Women have been sharing spaces with these people for years on an honour code system with no problem.
I cannot ever envisage that the current cohort of transgender activists could ever see things from women’s point of view. I have seen nothing to even make me have the slightest inkling that these people care about women. In fact, I see the exact opposite - I see a group of men, who patently detest women, who want to wear womanhood like a costume.
If you can be born a male, then say you are a female just by your words, it makes a mockery of what it is to be female.
THAT’S what’s got us adult human females angry. We wear the scars of womanhood on our bodies. The bodies that grew breasts and had periods. The bodies which suffered the embarrassment of flooding menstrual blood through clothes, miscarriages and the blood that comes when you wipe the day after the too-rough sex that you never consented to but were too frightened to stop.
The bodies that wished for babies and couldn’t have babies, made babies who couldn’t be born, bodies who became pregnant, had abortions, never wanted babies. All these female bodies, doing what female bodies do. Just a few of the many reasons why trans women are not, and never will be, women.
You don’t get to dress up as a poor fascimile of us, police our speech, tell us to enjoy our erasure, tell us we can’t use our established language to describe our anatomy and experiences, tell us we’re making you feel “unsafe” just because we’re talking, tell us we shouldn’t and in actual fact we CAN’T exclude men, and think we’ll just roll over.
We’re women. Adult human females. We don’t have penises and we don’t want them in our spaces. We won’t shut up and we’re not on the wrong side of history.
We see you.
