I grew up on a farm. I know how non-factory farming goes. Factory farming can be inhumane, as can some slaughterhouse and feed lot operations.
The "little idyllic farm" is far from rare. I don't know what part of the country you're in, but my employer runs one, my father runs one, my uncle runs one, and so on. There's nothing inhumane going on on their farms, I'm sure, and in my area, they are the norm. Many people here are part-time cattle ranchers.
I've slaugtered animals myself. I'm not a fan of the "knocking" that goes on in your typical slaughterhouse, but I don't consider it inhumane. Bleeding to death is not a painfull way to die. The animals are hung to expedite the process.
If you think I'm "hiding" from anything, you're mistaken. Are you hiding from the fact that humans are omnivores?
I've read and even posted in that thread you're linking to. If people don't want to eat meat and dairy products, more power to them. If people want to protest factory farming, fine. I don't like them, either. But, you're never going to convince me that eating meat is immoral or inhumane, unto itself.
