Why do Americans think the French hate them?

When I debated with Americans on this site, they says me "You French you hate us, but we saved your ass during the second world war". And honestly I wonder on what basis this observation, I have never heard a French say something bad about the USA, better many of them will dream of being part of the American empire as we used to be part of Roman Empire. Tell me your opinion about it lol
