Seems to me a rather fact-based analysis as to possible geopolitical role of these silos. where is the phobia?

Of course China can be criticized, but lots of Americans think the USA is a force for good in the world, fighting against the "evils" of these other nations, while never reflecting on our own similar evils. That's what makes it irrational. The USA is A) already powerful, B) does the same with our own ethnic and racial minorities (e.g. the extremely racist criminal justice system and our centuries of poor treatment of indigenous Americans, just two of many examples), and C) has states like Florida continuing to cover up COVID. Pointing this out gets called "whataboutism" because many people have the romantic idea that the USA is a force for freedom and justice in the world, an idea that is demonstrably untrue.

The sins of the U.S. are many, but I don't think anyone can credibly say, in the modern era, that the treatment of minorities in the U.S. is in any way, shape, or form comparable to what's happening in China right now. Say what you will about the U.S., no one's getting put in camps.

We put people in prison because of race, because we choose to enforce some laws on people of certain races and not on others. Slavery is allowed as punishment for a crime (see the text of the amendment) and that's exactly what we do with prisoners. When people of certain races are executed by police, the officer(s) do not usually face consequences or punishment.

We're the world's biggest glass house, maybe we shouldn't throw so many stones. We can set a better example by changing how our society operates, we only need to choose to do so.
