There's a Dutch page showing a disznótor. That's a traditional slaughter of a Mangalitsa pig.
One thing I like about such events is that they remind people that meat comes from living creatures. Unless you eat scavenge and eat things like roadkill, you have to deliberately kill animals in order to get their meat.
I think the more people think about the necessity of deliberately slaughtering animals, the better it is for people like me who sell the best-tasting meat. I have often reflected, while eating Mangalitsa, "I would so totally kill a Mangalitsa to get its meat." And I know how cute they are. Everyone who raises them knows how cute they are - and how great they taste.
