The very real implication is that Anakin is an online conspiracy theorist who generally always arrives at the conclusion that Jewish people control the world.
He's making fun of antisemitic conspiracy theorists. When somebody doesn't make a hamfisted soapbox of "HERE'S AN EXCRUCIATING EXPLANATION OF THE JOKE AND MY BELIEFS" that doesn't mean we assume they're a nazi.
My interpretation is that Lucas made it out to be entirely the evil Sith destroying an otherwise reasonable galactic social order. When in reality, fascism happens with no magic required.
