Again. You don't understand that sociologically, sexism is an attribute of a system of oppression its not just thinking that women are inferior to men (that the basic understanding of sexism not the complexe one). Meaning that by bodyshaming a woman, you are expressing this oppression on her.
So yes, by bodyshaming a far woman, you are being sexist (and fat phobic, but that's other debate)

Sexism is not related only to sex but also gender. I know you have a hard time understanding those concept, but make an effort here please.
