These are NOT bright people. They actually think the word “jewelry” derives from the word “jew.” Zimmerman sounded Jewish, so he became Jewish. It’s actually a German name. I’m sure the black underclass still believes the man is a Jew.
Now that's an understatement. If you are familiar with the classic work of Murray and Herrnstein from the 1990s, "The Bell Curve," you can see how prescient they were when they warned about catastrophic societal consequences stemming from ever-increasing masses of dummies in the general population. Of course, they were derided by the Left as "racists," so public dialogue on their theory was curtailed in the MSM back then.
Zimmererman sounded Jewish, so he became Jewish. It's actually a German name.
Many German surnames are also not uncommonly Jewish names, primarily because of the similarity between the German and Yiddish languages. (Yiddish was often the native language of Eastern European Jews before their mass migration to the US and the West in the late nineteenth and early twentieth centuries.)
"Zimmermann" means "carpenter" in German, and is a fairly common German surname shared by some Jews. In some instances, such as in this case, the final "n" was dropped in the spelling of the name to Anglicize it. But, as you said, and I agree, these reflexive and ignorant Jew-haters gloated in falsely tarring George Zimmerman as a "Jew" because it fit in neatly with their hate agenda.
