I'm not american but afaik it's very common. The US is on a different level though, see the flags in the suburbia, the pledge of allegiance in school's every morning etc.
But I'd say it's not "too much nationalism" rather the average american is defintiely more patriotic than an average european (who can then again be anyone from the UK to Poland to Moldova) but you get my point
