I just speak for myself when I right the following things.
By traits, I am going by the assumption of being like personality traits. Not like anatomical, social, or even behavioral traits. If you do mean traits in that sense, I will change my vote to Yes.
I voted NO mainly because I dont think gender identity even if polar, has exclusivity to traits. I do think that there are such things as feminine and masculine traits.
I dont think having traits from the other genders (plural) changes your own gender (identity), unless you think, feel and believe you are that gender. But I separate gender identity from sex, expression, behavior, and social interactions.
As for gender behavior and gender expressions (walk, talk, dress), I do think many do believe there are masculine and feminine types.
I think those that break gender norms, especially public, also help themselves and others to widen and expand the behaviors open, acceptable, and available to a person.
Certainly one may not feel like they belong to their body.
