I wish more cis women would understand that the way society treats trans people is inextricably related to our rights as women to individuality and self-determination and to our ability to freely exist in society.
The idea that trans men are "lost" women should tell you that they believe that your feminine body and your existence as a feminine person is something you *owe* to the world. If you cease to perform femininity, you have taken something away from others that was rightfully owed them.
