We Americans suffer from flag inflation. We mostly don't even notice them anymore, so people have to put bigger and bigger flags to prove how patriotic they are. I was at a baseball game last weekend and only noticed midway through how many (and how obnoxiously prominent) the flags were. It's silly.

OTOH, many immigrants fly the flags of their home countries, I guess as a sort of badge of identity. For whatever reason, that's always seemed less ridiculous to me.

Another thing I've noticed from US TV & films (so it might not actually be true), is how it only seems to be the US flag that is flown. Here it's not uncommon to see flags from lots of countries. Only governmental buildings would "only fly the local flag".

What is a "USAian"? Are you really so ridiculous as to believe that "American" is not the correct term?
