Firstly, some Americans (and some British, Irish, Germans, Aussies etc) can be loud and obnoxious. I have encountered them in France and elsewhere. Thankfully, like most holidaymakers, they are a minority. But the stereotype of the camera-wearing, baseball capped ‘Yank’ who sorts problems BY SPEAKING MUCH LOUDER does exist. As does the loud German, yobbish Brit, drunken Scot.....
I have rolled my eyes, mumbled under my breath and made ‘snide comments’ to French people about loud and obnoxious Americans on holiday. But I dont think all Americans are like that. Just that individual or family.
Secondly, makes your own mind up. I like things and places my parents dont. France is a beautiful country, Paris probably the greatest city on earth, and is well worth a visit.
