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.
