Well, I can't say how stupid 'city people' in the States are, but here we learn where the meat comes from in school. We watch films, we visit farms (one step outside the city and bam there is a farm and a forest where hunters hunt real animals and us dumb city kids learn where the meat comes from). We have a market where pheasants and hare and around Christmas even deer and bore hangs on hooks, bleeding on the ground or in a bucket. If I had wanted I could have learned how to hunt and fish an be a real manly man although I'm living in a city. Stupid me didn't want that.
So if one is disgusted with dead animals hanging in the butcher's window or on the market, they shouldn't eat them, it's not as if we would die without eating meat, even if some think they might.
