trans women do not only start to experience oppression or harassment when they start to present as women, and trans men do not stop experiencing oppression or harassment when they start to present as men. when you exist outside the status quo of the sex and gender binaries you experience these things constantly through your whole life, both before and after transitioning. the idea that trans women were "socialized male" and so grew up not experiencing sexism is bullshit. the idea that trans men have as much privilege as cis men and get to just stop experiencing sexism when they transition is also bullshit. both these statements are transphobic and are meant to diminish our experiences
This also implies that no men experience harassment ever and that's just wrong. Men harrass other men who in their opinion look a bit too left or femme or gay or not-from-here. Women harrass men who look a bit too left or femme or gay or not-from-here.
Please for god's sake stop perpetuating this notion that somehow all cis men are immune to being harassed, threatened or hurt in exactly the same way women, trans people, and everyone else is.
