French Official Language for EU?

Now that the UK is leaving due to Brexit, France wants to make French the official language for the EU. After all, French used to be the language of diplomacy in the past. But I think they want it to be French so they can evince revulsion at hearing others attempt to speak French, and to contemptuously correct everyone's pronunciation and grammar publicly all the time. They seem to enjoy the opportunity to do that greatly. (That probably accounts for all the wars in Europe over the years: Someone tried to speak French, and the French made that just smelled some horrible aroma face and proceeded to contemptuously ridicule everyone's pronunciation and nit-pick at everyone's grammar in front of everyone else and created hostility all over the place. In fact, maybe that's why Napoleon wanted to conquer Europe: to make everyone stop mangling their language through military force.) But think of all the time and effort the French would save themselves if they just spoke some neutral language instead as the official EU language.
