That very vocal section who glorifies death and violence are the same people organising, participating in, and attending the parades.

-Source, my feelings.

Countless people participate to acknowledge the efforts and sacrifices of those who died serving their country. Even when we were taught about it in schools the focal points were sacrifice and mateship of those that served and still serve. Present day service members also attend to acknowledge those that came before them. Plenty of it is nationalistic nuthugging but your willingness to just make up generalisation and whatever claims to suit your point is frankly just gross.
