Got told I'm too blunt in my performance review

I had my end of year performance review which was raving, but they always slide in one negative comment so we have an "area for improvement". Mine said I am too blunt. One of my other female co-workers got told she speaks her mind too much.

So when men speak up and participate fully, they are assertive, direct, and have that "get things done" attitude. But when women speak up we are blunt and speak too much. Frustrating.

I have autism so it's like they picked the one thing that would be the hardest for me to work on. I already mask heavily at work. It's very difficult navigating social nuances of a professional job being a woman and being autistic.
