Are you Chinese? You being offended by his post makes me feel like you are. He wasn't forcing his oppinion on you.
Also godel's theorem doesn't have anything to do with this, as godel's theorem is about mathematical systems.
Let me explain a little more about where the insulting comes from. During daily conversation people usually omit many relevant consensus details: context and premises. Otherwise communication would be extremely redundant.
One thing is important is: anything put into premise that other conclusions can drawn from, should be relative facts which all the parties agree. By providing personal belief as premise to draw other conclusion without explicitly stating that’s just personal belief means the “evidence” provider cannot tell the difference , unintentionally and implicitly force others reasoning within “evidence” provider’s own axioms system, without knowing there’s totally different axioms system with other premises exist.
In short: There's no problem at all to express personal opinions. However put personal opinion into a premise to draw other conclusions during reasoning without explicit emphasise is not good.
About Godel theorem, strictly it’s only about Math. You are right on that. I’m half joking but it’ an analogy. In sports field there’s a referee because if one team can act as authoritative way to claim they own truth implicitly gives the other team the same authority which will lead to chaos. There’s a parallel relation here.
EDIT: typo and grammar fix
'In 2006, allegations emerged that a large number of Falun Gong practitioners had been killed to supply China's organ transplant industry. An initial investigation stated "the source of 41,500 transplants for the six year period 2000 to 2005 is unexplained" and concluded that "there has been and continues today to be large scale organ seizures from unwilling Falun Gong practitioners".' [1][2]
'In December 2005, China's Deputy Health Minister acknowledged that the practice of removing organs from executed prisoners for transplants was widespread.' [3]
'China Daily reported in August 2009 that approximately 65% of transplanted organs still came from death row prisoners. The condemned prisoners have been described as "not a proper source for organ transplants" by Vice-Health Minister Huang Jiefu...' [4]

I totally respect your strong belief about the story. But don't enforce others accept your personal opion by imply your personal belief is truth. It's quite insulting.
