He's a Jewish banker. It's a dog whistle for the extreme right wing. Some people thinks he's the far right bogey man like the Koch Brothers are to the far left but there's an extra layer of anti-semitism attached when it's heard/read by certain groups. It's not just that he funds causes that are antithetical to the far right but the fact that he's a Jewish banker -- the favorite scape goat of various groups throughout history (both far left and right have targeted this group). It's gross and disgusting.
