The thing about whether a TIM experiences sexism, in real life, is rather moot.
There's not a TRA on the planet, who doesn't immediately, purposefully, tell you they're one. And in the exact same breath tell you that TIMs experience sexism.
So the sort of TIM who will tell you they experience sexism, is the sort of TIM who goes out their way to let you know they are a man, and therefore can't experience sexism.
Then you have those who tell you that they definitely pass.
I have yet to see one. Even Paris Lees, Caitlyn Jenner, India Willoughby, have got male written all over them. They have spent thousands of pounds on trying to pass.
Women are programmed from an incredibly early age to identify male pattern behaviour and male pattern mannerisms.
Rape and sexual assault survivors, even more so. Their radar is on a knife edge. Because their very lives would have depended upon it.
Even TIMs who transition very young, tend to be above the average height of women. Walk differently, have certain features like a more pronounced browbone.
This new wave of children who are transitioning might change that. But even a few minutes watching Jazz Jennings makes you pause.
What you see in a photo, that has been photo shopped, isn't really what you get in real life.
Coupled with that, women are socialised not to say anything.
There are loads of TIMs who will tell you that they pass, because everyone thinks they're a woman, but a quick glance at the photo will tell you that no, people are just being kind.
And AGP individuals who look like a navvy in a skirt, have an internal image that is wholly at odds with what you actually see. They see sexy minx, you see alpha male cross dresser.
So you are left with a few, very few, men who genuinely pass and who won't tell you.
You've then got to rely on them to act in a way that is counter-productive to their own benefit. So if they are of childbearing age, and it looks as though they are getting passed over for promotion, you have to rely on the fact that they will maintain they are a woman, despite it affecting their promotion chances.
Likewise sexual harrassment. Link below to demonstrate.
Nonetheless, you will see 'sexism' used relentlessly as a form of 'credential' to underpin the demand that they are actually women.
It's such a minuscule possibility, that it shouldn't form any part of the argument.
It also rides rough shod over the concept of oppression. Oppressors cannot identify into the oppressed group. Because, at any point, they can change their mind, if beneficial. Which is why they're not oppressed.
Think Rachel Dolezal.
