The British food thing is I think less about respect or fanciness and more familiarity. American staples tend to have similar ratios of various nutrient groups, often without even as much as a substitute. American "home-style" cooking is almost identical in a lot of respects, if we ignore regional variations in both countries.

So I think its less that we think French cuisine is fancy or British food is bad, and more that we don't even really think about British food because a British Christmas dinner is basically the same as an American one (and I've got no clue what a French person would eat for Christmas dinner, so it is exotic and expensive sounding in that respect).

Of course all of this mostly applies to everyone in any anglosphere country. I don't think an Australian would be any more uncomfortable eating a home cooked American meal than an American would be eating a British one.
