It was also the genesis of city-state cooperation in Eorzea, the first time they all came together to fight a common foe and led to where we are now and a common Eorzean identity. It was also the genesis of the Bard job, which spread patriotic stories about the war to years to come, and the Lancers' Guild, which still exists today. And for years after the war, Gridania shared a long border with a belligerent, militaristic, and unstable nation whose main export was mercenaries and then after a purge, civil war, and invasion, they exported refugees and Garlean spies.
After the war, Ishgard and Gridania even held reenactments and mock battles in celebration every year, so it's not like it's something that disappeared from the public consciousness.
My point was that Gridanians view all outsiders with suspicion. But I would imagine that with the history they have, Ala Mhigans already have more baggage than a Lominsan or an Ul'dahn in the eyes of the average Gridanian citizen.
The fact that we have a whole questline around a guy being angry about it shows that some are less OK than others. While I'm sure many Gridanians are accepting, Nourval wasn't alone, he had a whole band of people with him that hated Ala Mhigo. Though the majority probably lie in between the extremes of him and Beatin. In that questline one of the NPCs even says that Gridanians are already grumbling about Ala Mhigan liberation. The point of the story arc is to stop Nourval because he would fan the embers of mistrust specifically aimed at Ala Mhigans into a diplomatic crisis.
