I will have to side with
@ChristineM on this one. Such videos are very disturbing to her. I can understand that. She told you how to find them. Instead you demanded that she do something that she told you was offensive to her.
Now I grew up on a farm. I have hunted for my own meat. So I am not so upset by those videos. If you still want to see videos of halal or kosher butchery I could find them for you. Stunning is not perfect either, but here is the important part, it does lower the odds of a botched painful death. I am sure that one could find stunning videos that went wrong too. The problem with both kosher and halal butchery is that the animal is always conscious. They do not instantly become unconscious from the cut.
If you ask I could provide you with links to such videos. Most probably won't play here since they are often rated adult due to content material. Do you really want to see such videos?
