I'm convinced they know what the ICC is as it's even spelled out above, they just ignore the uncomfortable arguments.

The ICC is the International Criminal Court [0], which is "Trying individuals for genocide, war crimes, crimes against humanity, and aggression". The US is not a part of it after formerly withdrawing about 20 years ago. It shares this position with other countries with strong human rights values like China, Sudan, Indonesia, or Israel.
Moreover the US has passed the infamous "American Service-Members' Protection Act" [1] (also known as the "Hague Invasion Act") which authorizes the President of the US to use "all means necessary and appropriate to bring about the release of any U.S. or allied personnel being detained or imprisoned by, on behalf of, or at the request of the International Criminal Court" and also prohibits the United States from providing military aid to countries which had ratified the treaty establishing the court. This has exceptions if the countries in question already have bilateral agreements with the US to the same effect. The US went as far as to criminalize anyone who works for the ICC [2]. None of this can possibly be in the interest of justice but only to protect the ones who violate human rights as long as they advance US interests.
Since the US does not itself punish or even acknowledge any war crimes commuted by them you can see how this is not a matter of "we can't have others punish our people" it's just "we can't have anyone punish our people". There's only one reason for the situation to look like this and that's quite literally to be able to commit war crimes with impunity.
If you were looking at things that put countries like Russia, China, Israel, and others at the exact same level, it's the ease with which they commit such atrocious crimes and go unpunished. But with "due process". That should tell you everything you need to know about their actual values, not the ones claimed on a forum by people who selectively ignore whatever doesn't fit their world view.
