I’m pretty sure by white he means white, non-jewish europeans which also includes white americans since they’re from europe aswell but wether jews are considered white depends on who you ask. I believe that most jews don’t think of themselves as that either, though some do. I’m guessing it has something to do with being an oppressed minority. Then again white supermacists for example don’t consider them white either because they’re not “pure” or something.

I don’t think there’s any conclusive answer to this. In my opinion focusing on skin color is a stupid question to begin with. Asians aren’t generally considered white either though they seem pretty white to me. Friend’s wife is black but her skin is barely darker than mine. Go figure.
