Merely mentioning some general knowledge of stealth-shaping is insufficient.
1. Are you implying that Chengdu didn't make comprehensive simulations and measurements of J-20's RCS as a whole structure?
2. Are you implying that Chengdu didn't simulate and measure such, with the canards at different positions?
3. Are you implying that the J-20 can't be operated with penetration mode as well?
All the supposed problems that you mentioned aren't unsolvable at all. And you have yet to *quantify* how the carnard config is compared to the tail config in terms of RCS, to make your argument.

You could just build the canards out of radar transparent materials (the same thing you build the nosecone with) to get around the RCS problem, or at least mitigate it significantly (you can't do the same to the rest of the fuselage, because unlike the canards, they have inside things like the pilot, fuel tanks and engines which definitely have very large RCS readings).
Of course, those composites might not be very sturdy, so the PLAAF would probably have to swap out the canards constantly if that's the case.

Bad news for china. What is the status of the WS-13 engine?
Are those glassy materials structurally strong enough to also replace (with periodic swapping) the vertical tails of the J-20, which are relatively small? If yes, then the RCS would approach that of a "flying wing".
Please repond in the J-20 thread, so that we don't derail this one.

That's a politic and from Mao. Chinese people have a very very long memory, most still remember (not angry) what the British had done in the past. What the British had done in the past to China was really very bad, I can't imagine how would all Chinese would forgive the British.
one of many very bad events by the British
Well, their envoys were imprisoned and tortured. You can't really expect them not to take punitive action, especially considering the unequal strategic position between the Qing and British empires. Now the forced importation of Opium into China.... that's another concern entirely.
Personally I see this all as water under the bridge; to me the Ming and Qing empires represent the nadir of Chinese history, and the humiliation comes as much from the inability for social, political and economic change to come about for over 200 years (simply compare Qing to the Meiji Restoration), as from the treatment by foreign powers.

Excuses , excuses for barbarous behavior. just because you are weak does not in anyway justification for the strong to take advantages of the weak. When China rule the wave in 16 th century Century she didn't come, invade and robbed South East Asian kingdoms. To this day the Malay still remember, When ask why Malaysia didn't afraid of China , Mahathir answered we know from history China is not robber that come to enslave other people. Instead to this day the temple of Cheng He is full of worshipper both natives and Chinese praying for good luck and health.
I say forgive but never Forgot learn form history and keep the granary well stocked and sharpen the sword!
To put the blame on the Chinese for their humiliation is best disingenuous. Every Civilization rise, bloom and eventually died down . The Roman , Egyptian, Greece civilization are all gone . Next will be the Japanese, and the west. But China still there and now on the road to reclaim her rightful place again in history
