That paragraph responded to pwno's statement:

Maybe if it was proven that a lot of animal suffering goes into the meat I eat, I might stop.

If you're not curious, that's okay. As for fair presentation, I don't doubt that PETA and its less insane friends heavily skew every piece of evidence that passes through their hands. However, the amount of skewing I can believe went into a mountain of video documentation is necessarily limited by the fact that I don't think PETA et. al. are staging elaborate scenes of animal torture for the greater good of our noble friends the chickens. Take from that as much or as little as you will; it's certainly at least weak evidence that bad things happen to food animals between entering the world and leaving it.

Are there any non-partisans trying to find a middle position and present a balanced view of the issue?

If you find any, let me know. Everybody eats, so everybody has a stake in the issue: there is no way to be sure that an omnivore isn't being defensive or a vegetarian isn't being self-righteous if they come up with the conclusions you'd expect. I would be surprised to find an omnivore who concluded that food animal conditions were bad enough to warrant not eating meat; most people aren't equipped to make that kind of admission. Some vegetarians are, or claim to be, vegetarians for reasons unrelated to animal welfare - but they probably would not be inclined to invest time and care into crafting a nonpartisan analysis of the meat industry.
