I think that might play SOME role.
But, for example, I have a neighbor family from my former neighborhood (Putnam Lake, NY) who's father is a Scottish immigrant who lived in the Bronx, and who's Mother is Scottish & Irish descent from Queens.
Their kids are super Liberal.
For example, all 1 of their kids does on Facebook is complain about Confederate memorials, and praise Black Lives Matter, and constantly bickers about prejudices against Blacks.
He even said when a Black killed a little White child (Recently) t wasn't racist.
On the other hand, I have on Facebook many Italian Americans who live in Putnam Lake, NY & they are largely from Bronx & Yonkers families, and a lot of them are racist & or Conservative.
Actually, 1 of them is an Italian American, who grew up here, and I know attacked a Black Jamaican immigrant, for no reason in the park.
