Abstract
This article compares how Europe Day and the fall of the Berlin Wall are discussed on Twitter/X in Slovenia, Italy, Germany, and France. We treat these public events as commemorative cues that prompt users to interpret contemporary political conflicts through salient European historical references. Using an LLMassisted three-step design, we identify whether posts are conflictual, whether conflict takes an antagonistic or non-antagonistic tone, and whether it contains DQI-style deliberative signals such as justification, reciprocity, constructiveness, and respect. Topic modelling identifies thematic hotspots where conflict, antagonistic tone, and lower deliberative quality concentrate. The findings show that antagonistic tone generally lowers deliberative quality, but does not automatically eliminate reason-giving or constructiveness.
