So I've had similar hypocritical thoughts. This is what I've concluded, cis women don't need to justify their gender, we do. Look around, baggy sweatshirts, sneakers, frumpy pants, hair pulled back out, no makeup, no jewelry. People see them as they are but the dozen little things, no facial hair shadow, bone structure of their face, their stance... basically the micro little things that we (MTF) didn't do for years say "woman"
We need to show the big things so the little ones are overlooked, we hope.
Just my opinion.
