> "french are despising non native speakers, especially the Parisians"
I don't judge if this is right or wrong, but I lived in south west of Germany for a while, where they teach French starting in primary school.
Among the people there this is a common concept.
For whatever it is worth, I had actually good experiences in France including in Paris. Or, basically normal one, not really different from trying to get around Germany.
I suspect that French are unfriendly meme has taken life on its own. People complain when the French switches to English for them, they complain when the French speaks more slowly and simplifies the language, they complain when the French does not simplify for them.
