I feel like people miss the point of the "war is bad" message
What it's supposed to mean is that war is terrible, it's destructive, it ruins lives, it leaves scars, and you should only partake in it when there are no other options, because even if you win, even if you survive, you will not be the same, which is why the phrase used to be more commonly known as "war is hell"
But "war is bad" seems to have been construed by people in fandom into "any fighting is bad, if you fight you're morally terrible and impure, you should not fight at all, no matter what", this is annoying in fandom, as it often misses the point fiction is trying to make, but what's worrisome is when people apply this to real life, as I have seen people do regarding russia's invasion of Ukraine
And that's almost never the point of "War is Bad" works
Works like Lord of the Rings, Avatar The Last Airbender, Transformers, The Clone Wars, Halo (especially Reach), etc all have themes on how horrible war is, but they categorically do not say it is wrong to fight, what they say is usually along the lines of "war is terrible, and what makes it so terrible is that we have no choice but to fight, it would be ideal if we didn't have to fight at all, but we must fight, because not fighting is not an option, because not fighting, not opposing tyranny, conquest, and evil only allows those things to exist unimpeded"
