I am just pointing out that simply by having a big manufacturing industry doesn’t mean that you have a strong enough of a manufacturing industry. As well that there are critical industries and sectors where the Chinese economy is not world leading.
It can be both true that the US (and the West) has a weak manufacturing industry and that China doesn’t have a strong enough of a manufacturing at the same time.
Is this so difficult to accept as reality?
I've already said my part as to why I think the discussion has become what it was, and it was because your were entering the discussion with a set of assumptions that in any reasonable context, you should have had the responsibility to flag at the beginning.
By only flagging it later and with an air of arrogance as if assuming that others should already have known it or portrayed it as if it should be a default assumption, it creates animosity and a lack of interest in people to engage you on friendly terms.
For what it's worth, I don't necessarily disagree with what you're saying but you really came in hot and the nature of the subsequent reaction from people is also entirely logical.
