Being injected with estrogen doesn't give you the in-group bias that controls their decision-making.
That's why they are repulsed. Their brain is telling them "that's not a woman, they're not part of the in-group" and they're forcing themselves to override that.
That's why women have such an angry reaction to transgenderism when it affects their lives - because they're wired to support solely other women and their brain is telling them that these people aren't women and therefore aren't part of the in-group.
In short, all they'd have to do to move past it, is treat everyone the same way they treat other women. But that will never happen.
