...and ultimately even prevent the killing of animals for food.
...there are the rights of vegetables to think of also...!
The people who are really behind the movement towards the total control of everything remotely connected with the handling of animals are actually vegans, but this is not yer archetypal anxious vegan twitching her way along the supermarket shelves searching for shreds of evidence of meat based product contamination in her daily intake of comestibles but rather she is a radical vegan anarchist (add a dash of feminism to taste) a particularly obnoxious breed of lifestyle evangelist who believes that her way of life, is the only way of life.
Luckily for everyone else their arguments are subject to
Reductio ad absurdum, the law of philosophy and politics that states in this case that their relentless pursuit of animal rights leads inexorably to the pursuit of rights for all living things, and this process will continue until they have denied themselves the right to eat anything whatsoever, and thus, they die.
If you ever have to argue with one of these people directly then just casually mention their leather shoes...
