Well, I wouldn't want to have to smell the meat smell. My aunt lives next to a beef processing plant and it smells like rotting flesh 24/7. I don't care whether it's pork or beef, whatever it is it's gonna stink.
I think what's going on here is partly concern for violating their Halal rule as well as opposing the factory for other reasons but hiding those reasons and rather saying that they oppose it only for the religious reason. No sane person would want a meat plant 100 yards from their house and they're just using every means at their disposal to make sure that it doesn't get built there. Is it fraudulent and deceptive, maybe, but I can't say that I wouldn't do the same thing if I were in their shoes.
I can't really say I blame these people, it's the fault of their insane religious leaders who won't even let them touch a package of pork that is hermetically sealed.
