If you're trying to show that all meat-eating is unethical, you need to point not to worst practices but to best ones. Otherwise, all you do is produce broad agreement that bad farming practices are bad.
In this regard, Jeff Robinson is on stronger ground, as he does this - he attacks the practices that take place in farms labelled free-range and organic.
So,
here, for example, is a dairy and beef farm where calves are left with their mothers for several months (dairy cows have been selectively bred to produce more milk than they need to, so there's still plenty left over to be milked). They live good open lives until the day when they are slaughtered, which they all are still - this is a working farm.
Seems to me pretty much the best practice a meat farm can employ.
