This HAS to happen on farms on a regular basis, but i can see why some people are angry. Why did they have to take pictures and some smiled when it happened?
The real issue for me is anesthesia. If the animal is put under and doesn't feel it's junk being lopped off, it doesn't bother me any.
Like I said, as long as it's done humanely, no problem.
Protip: "I'll show you my dick!" isn't a conversation starter on the internet any more than it is in real life.
