I’m Polish by birth, but I grew up in the U.S. and so I think that I can provide an unbiased opinion by virtue of growing up American, but in a European household.
Do Americans hate the French? Yes and no. Anti-French sentiment is much more common among the uneducated, unworldly demographic. There are both social and political reasons for anti-French sentiment, which in itself is a symptom of a larger problem.
There are a few reasons why Americans are perceived to “hate” French people. First, there is the American assertion that America is superior to every other country in every conceivable way, which, ironically, is most commonly spouted by those who have never spent any time abroad. This jingoism is responsible for far more than Americans’ dislike of anything French, and extends to anything foreign in particular, which in itself is ironic because of America’s diverse background and culture. The Melting Pot is xenophobic.
Secondly, the “hatred” of the French (and generally of “European” and “Canadian”) is used for political purposes thereby perpetuating the dislike of the French by those following a closed-minded “herd” mentality. I can honestly say that in my personal opinion, I have only seen this used as a political tactic by conservative (more specifically, Republican) politicians, pundits, commentators and radio talk-show hosts. Exploiting peoples’ fear of anything foreign and therefore “different” is used as a scare tactic in order to maintain the status quo, often painting the French is particular as socialist, stuffy, arrogant, homosexuals. The examples of anti-French sentiment are many: the “French” universal healthcare system; the assertion during the 2004 presidential campaign that Democratic candidate John Kerry had strong French ties (even devolving to the point where some politicians and pundits briefly began pronouncing his name with a French accent); “freedom fries” instead of French fries; airing video of the breaking and subsequent emptying of French wine bottles into the rain gutters in political protest.
I had spent a short time in Paris, France a few years ago. I traveled there with the common American biases of French people being rude and arrogant. I was almost universally wrong. The French people, knowing that I was an American who spoke no French other than “merci,” were kind, courteous, well-mannered and humble. Even from the Polish expatriates, whom I could understand, I discerned little if any anti-American sentiment. Any negative sentiment was directed at the Bush administration, not Main Street America.
