Look the animals are not flayed alive. They have to drain the blood before they can process the carcass. So even if the bolt didn't paralyze them they would not be getting flayed alive. Stripping the skin off is a very carefully done process (after all that's good leather) and no one wants blood stained leather. That's a waste.
Sorry, but I was given the tools by nature to eat meat, and eat meat I will do.
Well technically the tools we have now a days are very unnatural. We weren't given any tools like claws and the like. We were given a very advanced brain though.
But then again you can look into nature and see tools being used. Eagles drop turtles on rocks to break the shell (how humane do you think THAT is?), octopuses use sticks/rocks to open shells, etc.
And yes, I've been in several slaughterhouses. I've watched cows get slaughtered, pigs, sheep, and even a horse get slaughtered and processed.
As for the embryo getting slaughtered, that's a whole different topic as to when the embryo is technically 'alive' and sentient. Also wasting a perfectly good calf...I've not heard of that happening very often. The pure blood, yah I've heard of that but a lot of farmers would rather get the calf and sell it to a feedlot after its weaned.
I want to know what ya'll think the humane method of slaughter is. An axe to the neck? A bullet? I'm sure a lot of people would love to use a bullet, it's a lot cheaper than what they currently do and easier. But they've been banned from using bullets because they're inhumane.
Anyhow, 'I didn't claw my way to the top of the food chain to eat vegetables' will still always be my favorite shirt.
As to hunting, what would you want us to hunt with? A gun? That's unnatural. A bow? Still unnatural but closer. Crude bows don't always kill in one hit, not even close. Modern day bows with all the science we've put into them for maximum punch kill nice and clean but that's not exactly natural.
So perhaps a sharpened stick? Waste of meat, and would take tons of stabs to kill the animal. I can't imagine that being much more humane.
