There are real women who get called sir sometimes and they don't really care. If you're going to label yourself a true and honest woman yet look like Dauber from "Coach," you are only lying to yourself if you think you won't be misgendered repeatedly and often.
But that isn't the issue. They know that's going to happen because they know they look like men in skirts. They have to be angry about every minor slight that happens to them, otherwise there is no "movement" or "revolution" or whatever dumb fantasy shit they think is going on. Every doubletake a stranger gives them passing on the street is a microaggression steeped in racist transphobic white supremacy and must be stomped out, as opposed to the innocent side-glances of a normal person spotting a linebacker in a pink Invader Zim hoodie
