Australia, believe it or not, is actually pretty bad in this regard. The amount of xenophobia disguised as "patriotism" is pretty eye opening (well at least for me). I haven't travelled through the USA though, but Australia definitely was a shock.
I know Aus has more than a few issues surrounding xenophobia and race but... I lived in Perth for two years and spent six months on the road around the country. Despite the fashion for Southern Cross tattoos, it comes nowhere close to the US for sheer number of flags. I never noticed flag poles and flags in people's front gardens (for example) like I saw in Texas.
