"Seems to me that they don't give two shits about animals suffering"
"they love to make animals suffer"
"they see animals as non living beings"
"why are these practices seen as normal in places China?"
You are referring to 1.3 billion people ("they") thinking that animal torture is not just acceptable and normal, but encouraged. Pretty deranged behaviour if you ask me. You then go on to say that "I see the people who think it's ok as hard, and not having feelings like I do." Which implies that "they" are all somehow less empathetic and 'human' in their feelings than you are. Which is rhetoric that Nazis and slave traders used to justify their actions.
I'm not saying that you're a Nazi vegan, but that your thinking, when taken to its logical conclusions, runs along the same lines. It's one of the things I find most twisted about some animal rights advocates: that in standing up for animal rights (commendable) they are promoting a dehumanising message about large groups of people.
And don't try and backtrack by suddenly adding a qualifier that it's only 'some' people in China who believe these things. You already told me not to "try and say again that these beliefs are not widespread, because they are, it is well documented." Well documented in your own mind, I assume?
Then you make another sweeping, completely incorrect statement which again implies that the Chinese are, as a population, somehow more inhumane than the rest of the world: "most parts of the world [...] in fact have animal welfare laws in place'. Erm, no, 'most' parts of the world do not have animal welfare laws, or if they do they are not enforced: much of Africa, south America, central Asia, India and the subcontinent, the Middle East and SE Asia. Do you think many of these countries have sufficient and effectively enforced animal rights laws? Or perhaps, rather like China, they have authoritarian governments who don't want to know, or other priorities such as war, poverty, civil unrest etc. It's not that people in these countries don't care or that they want to harm animals. It's just that adequate animal welfare laws are, like many other things we take for granted in the UK, western luxuries.
I think you should find some compassion and understanding for your fellow humans before you start crusading for animal rights on frankly quite bigoted grounds. Animal welfare has to start with human welfare.
