Seinfeld is an assimilated, primarily Ashkenazi American Jew. Pretty sure he married a shiksa too. Granted, part of his family is recently from the Levant, but Maronite Levantines, Greek Orthodox Levantines & non-Arab natives of the region (largely J2s) are arguably white anyhow. No, he is no Alt-Righter, but he has at times pushed back against the insane, anti-speech totalitarianism of the Cultural Marxist left. That’s more than you can say for most WASPs. So, to summarize: he’s fairly light skinned, has light eyes, isn’t a total coward, & doesn’t appear to hate white people. Ashkenazis are borderliners of course. While only about 2/5 of their genes are native to Europe, they are intimately linked to the European continent & its history, whether they like it or not. Often their politics & identities make all the difference when it comes to deciding their whiteness. But for what it’s worth, he’s white enough for me.
