@hecate @Concerned_Catgirl Yeah you're absolutely right, it was on the Free France's flag during WWII and a symbol deeply connected to the General De Gaulle. There's a huge one in Colombey-les-Deux-Églises in the east of France where he's burried.
It's originally linked with royal families of eastern Europe (Lorraine has shortly belonged to Poland), it appears on the flags of Slovakia and on the coat of arms of Hungary and is a general item used in heraldic.
So of course it is a symbol of a very important (and dark) part of our history, but I don't see why we would favour that part rather than others. To me it's a historical event, not what defines France.
