I would not. I would also not have sex with a man, call a man pretty, buy tampons for a man, buy birth control pills for a man, marry a man, buy flowers for man, nor buy makeup for a man, among other things.
But again, I am not talking about all whites, or all women, or all middle aged people. I am only talking about a subset of white middle aged women who share certain characteristics. To simply recognize certain differences as racist or sexist takes those terms beyond all recognition.
The agreed upon (at least as I was taught) distinction is that you are stating or implying a belief in inherent inferiority of a group, almost always due to genetics.
I can say that blacks commit crimes at a higher rate than whites, but that is not racist unless I am arguing that somehow they are genetically predisposed to do that. I can say that there are more male doctors than female ones unless that belief is because those precious little dolls don’t want to break their fingernails.
Likewise to say that most people who do X are white middle aged women is racist and sexist is absurd unless I am saying that there is something inherent about both being female and white causes you, once you reach middle age, to do those things.
