From your points, I can infer that there are 3 kinds of Americans (and Westerners in general) which are actually eager and willing to go to war against China:
Kind #1 - Those who really thought that war is "fun-&-exciting" like Modern Warfare, Battlefields or CSGO, where they could just rush B, massacre as many enemy forces as they want, take multiple gunshots without dying, and without suffering from any war-related PTSDs.
This kind of Americans (and Westerners in general) are the least worrying. They usually are the first ones to run in the opposite direction when sh1t does hit the fan.
Kind #2 - Those who despise China and the Chinese people thanks to constant Sinophobic brainwashing by the West, and truly believe that by going to war with China, they are somehow doing God's work, and that they would "save and liberate those poor and oppressed Chinese from the evil SeeSeePee".
This kind of Americans (and Westerners in general) are certainly worse than kind #1, but still largely managable and can be turned around if their mindsets could be rectified in time.
Kind #3 - Those who actually hate China and the Chinese people to the very core, viewing China and the Chinese people as existential threats to them, and would very love to see the Chinese civilization state being wiped from the surface of the earth at any costs, even if the whole world is scorched by nuclear hellfire as a result.
This kind of Americans (and Westerners in general) are the most worrying. They themselves represent the most dangerous and lethal threat to the continuity and surivival of the humanity.
Unfortunately, the biggest problem we are facing right now is that the proportions of Americans (and Westerners in general) who are in the kind #2 and kind #3 categories have been growing exponentially larger, especially in the past few years.
This is what scares us, both Chinese and non-Chinese, the most. Why? Because the US, on its own, has the capability to end the whole world as we know it.
