You are correct, but public opinion is so out of wack on this topic that it is hard to have a rational conversation.

Several years ago I was involved in a zoning process in a rural county with many active farms on it. Coincidently, someone else was trying to build an abattoir to process horse meat. This is absolutely an allowed use in an agriculturally zoned area, and the developer just needed what should have been an automatic approval. Long story short, the county turned down the approval and more-or-less said “sue us.” So even though it was legal in fact, public opinion made it illegal.

As I recall, the abattoir was being developed to process horse meat for export.
