I haven't seen any polls on it lately, so I don't know the percentage of Americans who actually do hate the French. I'd guess that that percentage is smaller than you think. A large majority of Americans have never been to France and don't really know any French people. So they would probably have no opinion on that question.
The most common things that seem to tick off Americans about the French are (1) arrogance toward American tourists by some Frenchmen; (2) a feeling that France hasn't sufficiently repaid the US for saving her in both WWI and WWII - e.g., doesn't necessarily align herself with US geopolitical interests; and (3) in recent decades, France has admitted too many Muslim immigrants and tends to appease her domestic Muslim masses both in terms of her domestic law enforcement policies and her foreign policy toward the Islamic world.
I don’t know about polls, but I’ve spent enough time with Americans in Europe to know that I have to prepare for incoming when it is mentioned. I can set my timer for an anti French, some kind of frog slur nothing forum
To your points, why Americans think they can just go into a country not attempting to blend in, just viewing it like a zoo, and then dictate the natives’ reaction is a question that can only be answered one way
We are mad that they didnt pay us? Really? When is Iraq and Afghanistan going to pay? Why don’t we have rights to Iraqi oil? Do we hate them?
And we don’t like them for not respecting their borders? Go to San Antonio any given Sunday evening any shopping center. The ‘poor’ immigrants are reaping and there is not only no one speaking English there is no one with a modicum of respect for Americans nor America. The shopkeepers are happy. They couldn’t care any less about what they’re ushering in nor what it means to their country nor tge country of their grandchildren
It is hypocritical so I think people just hate the French because they find it enjoyable it takes their minds off how we are falling short
