Not obsessed, just curious, since you mentioned that it was a general opinion;
“Because they are seen, by naval officers, as an adversary and considered by them and others to be the bottom of the barrel.”
I know that if you have never had any dealings with people of a different race and nationality it is easy to form opinions that are not based on facts and own experience.I don’t mean meeting someone in a bar somewhere, but actually working with them.
Since there are few foreigners on American ships and few Americans on foreign ships, it doesn’t appear to be much opportunities for most American seafarers to actually work with anybody else, thus not really be able to form any opinion on their abilities.
Of course, when it comes to the US Navy, this is even more so, although they are stationed at what amounts to a small piece of Americana in foreign lands. They appears to interact with the locals with an attitude of superiority. (At least that is my experience from seeing them on liberty in foreign ports)
