I haven't seen the videos, don't know why my computer refuses to play them; but: growing up on a dairy farm I can imagine what they are like.
The killing of pigs, chickens, cows, etc....is no walk in the park. Taking saws to the big portions, pulling out the guts etc.....is not something the people who didn't grow up seeing such things are ever going to like...and then consider these chinese can now cut and dice up their own baby girls for lunch.........and have no problem eating 3 scream rats......
