At one level
At one level the organizers are right, it is ridiculous to complain about eating one sort of animal while eating another. (and yes I am a meat eating dog owner).
However, it is not really the eating of meat that annoys me so much but the barbaric practices around the killing. According to the Chinese the meat is better if the animal dies in fear and agony, for this they go to quite hellish extremes. They aren't the only ones, seems to be a far eastern culture in general.... using sledge hammers to slaughter cows is fresh in the mind from earlier in the week, and pumping large whales full of harpoons is hardly friendly.
No slaughter house is going to be nice, no killing is 'cute' or 'done tenderly with love' - I know I used to work in one when at college. However there are some limits in western culture and a desire not to make things worse than needed.... a total opposite to the eastern approach.
Perhaps people should remember this when buying Chinese made products... both directly or because so many of our manufacturers have most of it made in China and merely stick a label on in the UK.
