gness - what you must remember is that farmers and 'country folk' have a different attitude and perspective rergarding animals.
As non-farming / country folk people, we tend to view animals as intelligent entities, and often anthropomorhisise them to give them endearing 'human' characteristics, which makes us aware of their potential suffering.
Farmers / country folk have a very different attitude - animals are normally defined in monetary terms - they provide a cash return in one form or another, and this means a tandem absence of sentimentality. once an animial - even a domestic pet - is not longer useful of functional, it is disposed of.
This explains your local farmer's approach to the circus - he is simple renting land to people who regard the keeping of animals as he does - a money-making enterprise, sentiment absent.
Therefore he sees no issue in either the circus's activities, or in him renting land to facilitate those activies, and will be genuinlye baffled by anyone making an protest on the animals/ behalf.
Is it wrong? Yes, performing animals have no place in a modern civilsed society - circuses are dying out, and within a couple of generations, such activity will be consigned to the history books, along with children working in mills and mines - and that is where it belongs.
