Well, maybe he referred to me as we.
Please, don't be that salty, especially when you are talking about something you don't know that much.
If something has to account for the unacceptance of zoo in China, "I don't want my food to be fucked" is definitely some of the reasons least concerned.
The acts of bestiality in China are rare, and cases of bestiality known to the public are much rarer. Hardly anyone will think of the possibility that food on the desk has been fucked.
[The animals raised for food] and [The animals raised for zoos] are two groups which seldom coincide. The major coincidence is dog. You seem to overestimate the proportion of meat dogs(I hate this word) in China. There are several millions of them, while the livestocks count in billion. It is hard to calculate the total number of dogs in China, but that will also come in tens of millions. And, to an emotional point of view, dogs are mostly pets in China. There are many stories about them. When bring up cows, most people will think of beef and milk, but for dogs, they do not.
