Sensitive topics in France
The French like pleasant arguments, debates, and conversations in general, however some subjects should be handled more subtly or discreetly than others:
The opinions of French people on a wide range of topics are diverse. You should probably avoid talking about internal French politics, especially touchy topics like immigration, unless you closely follow French news; otherwise, you risk coming off as presumptuous and ignorant.
It may be helpful to read French newspapers to acquire a sense of the diverse range of political beliefs in France, from the nationalistic right to the revolutionary left. Having said that, don't let this deter you from discussing politics with French people; just be mindful of the disadvantages that come with being a foreigner.
Additionally, it is regarded highly impolite to question someone directly who they voted for in the most recent election (or who they plan to vote for in the one to come); instead, focus on the issues at hand.
