When the Chinese boys came on here, they made all kinds of outrageous claims about Chinese weaponry, many bordering on defying the laws of physics, especially when it came to 'stealth' when they want to diminish the technology. I politely presented my rebuttals, I stayed on subject and supported my arguments with credible third party and non-paywalled sources. My rebuttals were not meant to be comprehensive. It is not possible given the complexity of the subjects involved. However, my sources have relevant highlighted keywords for everyone to do their own researches to verify for themselves if my arguments are valid. These are very reasonable ways for any debates.
The Chinese boys here considers any challenges to their claims to be 'anti-China' and 'anti-Chinese', meaning they are tacit 'racist' posts. Basically, they grossly expanded the definition and contexts of 'racism'. They initially thought I was a typical white American with all the historical baggage regarding American history with institutional racism. But when they came into the fact that I was a Viet and a US citizen to boot, their own racism towards other and 'inferior' Asians came to light.
Bottom line is that the Chinese boys here, all probably conscript rejects, are overly sensitive to any challenges to their claims about the Chinese military and to think that an Asian could do those challenges well is simply unthinkable to them. To date, none could dispute my argument that I was initially polite in my rebuttals to their ridiculous and scientifically absurd claims. That ought to tell you something.
