Why does China deserve this?
China deserves this because it conducts a deliberate, long-term campaign of unrestricted covert warfare against democratic societies. It has not yet progressed to full-scale war with military means but it might well come to that if circumstances are right. At the moment, however, it is a a covert, multi-domain conflict that includes: economic coercion and market manipulation, intellectual-property theft and forced technology transfer, political influence operations, cyber espionage and information warfare, deliberately designed in a way to avoid triggering military retaliation (for the time being).
The entire Chinese system is inherently predatory, and we are only beginning to realise it. China is a monster that the Western capitalism created and they actually do plan to "hang the capitalists on the rope that they sold them". The Chinese intentional deception, coercion, and rule-breaking is exponentially more dangerous than Russia's playschool imperial ambitions. I'm not even going to mention systematic human-rights abuses by the Chinese, because they're communists and that's what communist parties do - that's their nature. What follows is intentional, large-scale repression as state policy, cultural and religious eradication (not just control), and total subordination of the individual to the state (in a way that makes USSR look like a boy-scout camp).
For Europe, both East and West but I think that also for Judeo-America, China is the very antithesis of what a civilisation should be. Power replacing law, humans beings reduced to means, truth subordinated to control, morality subordinated to obedience, silence over integrity, loyalty over judgment, conformity over wisdom and common decency. Even Russia in its darkest imperial instincts is still closer civilizationally to us than the Chinese. People who don't see it are blind but when they realise it, it might well be too late.
Blow-torching dogs alive before cooking them is just a cherry on top - a small aspect of Chinese culture but a rather revealing one.
Call me a Sinophobe and I will confirm - the c*nts are scary as f*ck. It might be shocking coming from a Pole but I wouldn't swap our border with Russia/Belarus for a border with China. Not in a million years.
