I keep trying to teach cis feminists: trans women are as close of an "A/B test" of sexism as you can get in society. We can give countless real world examples of sexism effects of THE EXACT SAME PERSON who has even more years of experience getting treated differently just because their public gender changed. You can't dismiss it as we're just "not as skilled" as our men colleagues or "not as assertive about getting raises and promotions" or any of those other excuses people will trot out.

The. Exact. Same. Person.

And so many of us see our careers stall. Our raises shrink. Getting talked over and ignored in meetings. Just because of our gender presentation.
