Indeed, people must remember that the meat we see neatly packaged in see-through packet in the supermarket has come from a living animal that had to have been killed at some point, in some way.
I think many people forget this.
The somewhat gruesome slaughter of livestock must (and will continue to) go on, in order to satiate our ever growing need for meat that we are happy to consume in its various pre-packaged forms.
As someone said earlier, I think Ramsey's disgust was more down to the fact that those were his "pets" that he was seeing slaughtered. Im sure he has been to many a slaughter house so under circumstances where it is not his own pets being slaughtered, he would probably take it all in his stride.
