Only in the sense that they concern "race" (and loosely, since here it's an ethnicity).

So, in the same sense that preferring to have sex with women (or men) is "sexism" since "Sexism is prejudice or discrimination based on a person's sex or gender."

Just not the kind of sexism that e.g. Weinstein peddled.

Just because we call what a bigot or KKK member does racism and making a comment that touches on ethnicity or race "racism" doesn't mean those are the same things, or that both are bad.

The concept of race is not looked on favorably in anthropology anymore, anway. It's better to speak of ancestry groups, as this does not imply biological homogeneity the way 'race' does. Besides, I think for a long time, the concept of race and ethnicity were tied up together, so, 'Racism' is an appropriate way to describe antisemitism, for example. Race is as much a social construct as ethnicity, so the distinction between them was loose from the start.

Stereotyping can be a tool of racism, but to do that I think it needs to imply the inferiority or superiority of an ancestry-group. It's not clear to me that holding a grudge is either a positive or negative quality.
