It might just be because I live in the Southwest USA, where a lot of folks are of Hispanic descent, but she looks mostly white to me. She reminds me of a Kardashian (in both looks and 'tude!), who are Armenian and definitely white. And the surname Zegler sounds.... Germanic Jewish.
I dunno, I remember when the first kerfuffle came up that the new Snow White wasn't actually white. But in the 2020's, when there are so many mixed race folks now, she certainly appears generally white to me.
Again, perhaps if you were from Duluth, Minnesota and didn't have a lot of Hispanics in your life you'd think differently, but she looks more vampy, pouty Kardashian to me.
But what do I know, I'm out of it, maybe
Kardashian is now considered a race and a protected class?
