Really? You have a completely pain-free life? How boring.
That's a good point, and I don't buy idealism/sentimentality about animal suffering. In past threads we've discussed that in the wild, many if not most animals would suffer a lot more painful death than the instant kill we provide for them. I grew up with former farmers and visited relatives (in rural Kentucky) who still lived on what they grew and canned and slaughtered and milked daily. Those animals had a great existence until their death, which was always mercifully quick.
But that is far from industrial meat production practices. Very, very sad indeed to see poor critters raised from birth in severly restricted spaces awaiting our tables.
