Just to put a quite different slant on things now i have RTFT (only read the first page before commenting, always an error!)
When I was a hunt sab, I was vegan, and had a very particular perspective on this - very moral high ground and very judgy.
Around 12 years ago having re-evaluated things, I started eating meat again, but only free range - so I eat a lot less of it than most people, unless I've had a very good month, or get given some by my DB who raises/hunts. There are sometimes occasions when this falls down when I eat a burger am only human. Rest of the time, when I can afford meat, it comes from a farm shop or Waitrose/other retailer who treats their farmers well.
I am just trying to point out my own hipocracy when I say... that I actually think unless, ethically, you're willing to butcher your own meat or accept the reality of it, then you shouldn't reallly eat it. I have - I've butchered chickens at my DB's house etc. I abhor the 'it just comes from the supermarket' mentality that many people have about meat, and when my DC is old enough to understand, will get that knowledge first hand, with all the respect for the animal that has died for our sustenance.
Foxes, OTOH, actively destroy and not for sustenance, animals we raise for slaughter. From a Darwinian perspective, what's wrong with culling them via dogs or any other method, in order to protect our own food source?
