This! But honestly it?s mostly Parisians that are arrogant. French from countryside are more laid back.
Depends if you talk about normal people or fans.
PSG fans are hum... There are different types : the old ones and the new ones now that we are mega rich.
Both take pride about the fact that most of them are still loyal fan of a french club contrary to the french guys taunting us because they just chose to support one of the historic dominant clubs (OM fans often known for supporting several big clubs abroad).
And as you point out the opposition between Paris and the country side is present in football as well. So, PSG fans have a siege mentality because they are all against us mainly. It is the opposite situation from Bayern in Germany. You have a PSG tax when you want to buy in France, everyone will laugh at PSG and its fans when they lose, everyone will dismiss their wins as Q$G. The national hatred is just being expanded worldwide now.
