And you will not understand until you recognise that your "identity" actually depends on imposing identities onto other people.
You are the one who decided there is a line between us and you, between what we are and what you are.
And just as you feel you have the right to be upset and hurt when your identity is dismissed, so others feel the same by what you are doing to us.
The difference is, to be very blunt, you started it.
We didn't redefine ourselves, you did that the day you decided "woman" meant something different to just physically female, something mental, something that you despite your female body are not.
And as long as you continue to insist, by your claim of a non-binary identity, that this definition of women is more accurate for us than the one we would use for ourselves, women will continue to resist.
Trans people started this when they decided their own sexist ideas needed to define everyone else as well. So only trans people can stop this. Do not demonise other people for complaining that you are stamping on our feet.
