To be fair though, flushing a toilet isn't really the same moral choice as slaughtering an innocent animal.
Nor is it cruel to keep toilets locked in small dark rooms, in an unclean state, chopping off parts of their anatomy (i.e beak chopping for hens), farm them intensely, pump them full of hormones and drugs, feed them an unnatural diet, seperate them from their young or use questionable methods to 'humanely' kill them.
I'm afraid you are talking about life (which is closely related to our own) and souls and that is a wholly different plane of moral standing (depending on how you view our animal counterparts). But I don't think I am wrong in saying that, mostly, human beings like to think of themselves as compassionate creatures.
Which is thus why it is strange and seems wrong for us to sell joints of pink meat in supermarkets far away from origin and not even question how the meat came to be.
Meat is a different thing entirely from shovelling poo, or switching on electricity. Because you are, as a human being, with the greater power and with the most responsibility, dictating what happens to the lesser lives. Of which you have no idea and never will of how they feel or see the world and the cruel practices inflicted on them by us.
It seems wrong then to be the removed person from the factory farming. And yes, I too believe that everyone should witness the slaughter of an animal by the common methods and then make a decision in regards to their meat consumption. I think it's a sound logic. Maybe not to do it yourself - but to be ok with what actually goes on. I wonder how many of us would be?
A lot of meat eaters have no idea what they are eating - they eat meat, they are proud of this fact and they have an 'I don't care attitude' to how it gets to their plate. As long as it does, in vast, cheap quantities. Some of it is little better than the rendered dog meat they put in pet food.
The ones that do care get some mixed messsages about it, and try their best and believe that buying certain labels removes some of the guilt, as they are assured it is 'friendlier meat'. But again, a lot of people just see the label and not what the label REALLY means.
I think everyone needs to be much more aware of what they are actually eating and how it came to be. We put too much faith in big suppliers and cheap prices.
