Thanks for this article. I think you're absolutely right that many people, including many Jews, were unfamiliar with the figure of speech he was using. At the same time, many non-Jews are unfamiliar with how this expression can sound to Jewish ears. The result was an online battle royale born of blind spots which only exacerbated tensions between our communities.
You may be interested in the article I wrote on this topic, from a Jewish point of view. (I also think Foxx didn't do anything wrong.) https://medium.com/@boazmunro/on-jamie-foxx-and-our-mutual-blind-spots-52042905dea5
