It's interesting to apply this criticism to a hypothetical man as well.
She's too bossy - he's assertive.
She's too friendly and smiley - he's down-to-earth and relatable.
She's too direct - he calls a spade a spade.
And then to look at some of the other stuff and reverse it - she smiles too much! If she didn't, she'd be called a misery, or accused of being snobby and up herself.
What it seems to boil down to is that she has committed the cardinal sins of being American, of mixed-race, confident, and having ideas. The horror! So she must be put into her place, quickly.
It's nasty, nasty, nasty.
