I’m a trans woman and I honestly couldn’t disagree with you more. There are plenty of men who present themselves femininely and there are plenty of women who present themselves masculinely. And there are plenty of people who don’t identify with the binary.
What you wear shouldn’t say anything about what your gender is. It’s simply a method of expression, open to all genders. Cisnormative society wants to put us into boxes based on how we look and what we wear, but it doesn’t have to be that way and many do not play by those arbitrary rules.
I don’t assume malicious intent when I’m misgendered until it happens repeatedly. I’d rather see it slowly become normal for people to ask which pronouns people use, than to perpetuate cisnormative gender roles and expression.
