Of course. The practical, exploitative implications of nationalism are most glaringly obvious when you consider it one of the most effective weapons at the disposal of political elites whenever they feel the urge to trigger a War. The collapse of America serves as the premier example, though that leans far too heavily into the realm of Politics, which would arguably move this entire discussion out of its current scope.
Since this thread is situated within psychology, the actual intent here is to debate whether a type of collective identity rooted in the concept of the nation is desirable or undesirable in a modern society. A useful case study for this discussion would be the Communist Party, acting as a relatively benign forum teeming with a brand of nationalism that most people find perfectly "charming."
Personally, I find no necessity for collective identity; I have never been one to indulge in group mentality, nor does it particularly excite me. However, I am perfectly aware that such identities must exist for those who require them. Consequently, looking at potential solutions, it seems far healthier, safer, and more tolerant to define oneself through cosmopolitanism—as detailed in post #20—rather than clinging to nationalism.
