I wonder why you white leftists keep promoting euthanasia for humans, yet have never advocated for euthanasia for stray cats and dogs?

Since cats and dogs are 'stray', it means no one is willing to adopt them. Anyone who wants to adopt can take them home - there are no laws in China preventing these 'compassionate people' from keeping cats and dogs. To put it simply, the supply of stray cats and dogs exceeds the demand for people wanting to adopt them, which is why they are homeless.

Also, what is the scope of your animal protection? Starting with cats and dogs, will it eventually extend to pigs, cows, and sheep? Are cats and dogs fundamentally different from pigs, cows, and sheep? No, right? For instance, pigs are actually very intelligent. So what is the ultimate goal of your animal protection legislation? Vegetarianism? Eating bugs?
