Hmm... I am starting to see a pattern here...
For some of the members, as soon as someone (irregardless of his/her background) say something negative or distinctively negative about China - eg. the Chinese still do not process sophisticated machinery and background, then they were all, "See. Even the Chinese admit that they are trailing behind! It must be true." or the Chinese aircraft have carnards... well... carnards must be bad. And when the Chinese are close to deploying stealth, then stealth must be back aerodynamically and conventional fighters with the help of ground radars and the such could easily kick the ass of these stealth fighters.
And whenever another person said something that distinctively or in their own imagination that contradict that believes, those same members will start questioning the credibility of the person, like, "ah, who should we believe?" and that the person who don't speak too positively of Chinese industry must be creditable because he don't sing praises of the product by his country.
However, that doesn't applied to other 'experts' (such as chief designer of some engine in Russia) that sing praises of the engines that were produced by the company that the chief designer are working in... .
Hmm... food for thought.
