One of the very first things I noticed in the female role was this feeling. The smarter I let myself seem, the less people thought of me. And yeah, not from arguing or whatever, I try to steer clear of that, just from simply revealing that I do have a brain. It wasn't overt, but I felt and internalized that feedback rather strongly, and while I got it from both genders, it was mostly men.
I learned to kind of play dumb at first, which I felt gross about doing. I don't do that anymore cause it's ridiculous, but I do still find myself just being less apt to lend my thoughts to a conversation to which I probably could add something because I just hate that feeling. It is one of those subtle things society does to women that keeps them in their place, I feel.
