I think you're being downvoted for having a negative viewpoint, but what you said is very accurate. I'm not French, but I've spent some time in France and loved it. France is a gorgeous country and people were generally friendly and welcoming, Paris is the exception. There are parts of Paris which are nice, but a significant chunk of the city is exceptionally dreary (partly due to architectural design, heavy use of brutalism, etc), dirty, and many people I encountered in Paris were very rude to me, even before I opened my mouth.

I've traveled all over the world, Paris is not anywhere near that bad compared to many places I've been, and generally I enjoy most places I spend time in because there's something positive to be found everywhere. But I wanted to reinforce your viewpoint, because it is not inaccurate, even though I find it to be somewhat one-sided. I don't believe sharing this deserves downvotes, especially in the context of the link.
