A silly article, the equivalent of one that writes about New Yorkers to represent Americans. And it ignores the fact that for more than a century, Paris has been overrun with rowdy, druken tourists - and then there were two German occupations.
The French, even the Parisians, are wonderful when you get to know them. Remember that Paris for more than a century was the international capital of the arts and of modernism, and that was in part because Paris welcomed, and made space for, artists and writers who could not find a place in their own countries.
I consider that to be more than hospitable.
I visited Paris quite a bit in the 80’s. I found many of the Parisians to be needlessly rude. I was attempting to speak French, but that didn’t seem to matter.
You are correct in that tourists can be rude, but we were not rude.
Some say that the French got their noses out of joint BECAUSE they were the center of law and culture, but those days are past.
Outside of Paris, I found French people to be more friendly, though still quite reserved.
I would still recommend visiting the country, as it is so interesting.
