I was the same way. I truthfully hadn't ever met/seen a Jew until I left home for New York when I was 18. Before that, I'd lived in a rural farm community with no exposure. I had no real reason to dislike them, but then I started seeing them being absolute scum bags in public, I also started to notice every director/actor is -stein, -berg, etc. I guess I just "got woke" one day after putting everything together and realized they're a much more clever enemy than the negro. The negro is the obvious threat, but the Jew is behind it, and is the root threat.
