Oh, there we go...
Another feminist rejecting human nature.
There are in fact two different sexes with different natural characteristics, and therefore the word "sexist"/"sexism" is preposterous, since it implies that it's wrong to distinguish the two sexes.
The natural is for men to be masculine, and for women to be feminine. When one of them begins to live in a way that is in disagreement with his natural gender, that means he's following an unnatural course in his life, so this cannot be seen as normal or as praiseworthy, though it can be tolerated.
You really should never use the word "sexist" seriously if you care for humanity and the preservation of sanity.
There's no "sexism" in what I wrote about Yamato. I pointed out that the fact that her personality is so masculine is bad because she is a female character, and the normal is for female characters to be feminine. What I'm saying is just common sense, that corresponds to the objective reality, as it has been acknowledged to be by by far most people since the beginning of human history, so you have no business trying to blame me for stating it.
"Speciecism" is a similar word, in terms of how destructive and against reality it is.
