I think you are on the right track with the idea that some work places (and industries) are more prone to use it, but I wonder what subset of the population work in those places/industries.

And I don’t care if farms are factory or not. I think most people could care less. What they want is convenience, environmental protections, regulations etc.

I think the people screaming about factory farms don’t know anything about farming and they think factory farms are forcing regular farmers out of business. What they don’t realize is the vast majority of regular farmers are well off. When you or I file for bankruptcy chances are we lose everything. A farm files for bankruptcy will more often than not continue operating.
