I also noseticed that, but as it turns out, it's not a cohencidence, but in fact an actual coincidence. The word that eventually became "jewel" in English, I think came from Norman French and had a somewhat different spelling, which was not similar to "jew" or "jude" or anything like that, and had nothing to do with jews. Someone can feel free to correct me on the details as I'm too lazy to look this up again.
I think there's a lot more jews than we think. They say 5% but they're so used to shapeshifting that they don't answer the question honestly and it skews result badly. I remember reading an article from a big paper that discussed this exact issue. The U.S. Census does not have jew as an option.
White, Hispanic or Latino, Black or African American, Asian, American Indian or Alaska Native, Middle Eastern or North African, and Native Hawaiian or Pacific Islander.
So what does a jew pick?
And this is the way they want it. They don't want the next census to be corrected, either, because they don't want to be counted.
But just walk into any senior care facility (aging jews can be identified easily.) I was in one recently and it really is a remarkable number. I would say 15%
